Primary 3 Mathematics Quiz - Money (Answer Key)

Total Marks: 40

Section A: Multiple-Choice Questions (10 × 2 marks = 20 marks)

1. A) $34.50

Working: (3 × $10) + (2 ×$ 2) + (1 × $0.50) =$ 30 + $4 +$ 0.50 = $34.50
Explanation: Count the value of each type of note and coin. Three $10 notes are$ 30. Two $2 coins are$ 4. One 50-cent coin is $0.50. Add them together:$ 30 + $4 +$ 0.50 = $34.50.
Common Mistake: Forgetting to count the $2 coins or misreading the 50-cent coin as 5 cents.

2. A) 8 dollars and 5 cents

Explanation: In decimal notation for money, the digits before the decimal point represent dollars, and the digits after the decimal point represent cents. $8.05 means 8 dollars and 5 cents. The '0' in the tenths place shows there are no 10-cent coins.
Common Mistake: Thinking $8.05 is 8 dollars and 50 cents.$ 8.50 is 8 dollars and 50 cents.

3. B) $17.45

Working: $12.90 +$ 4.55 = $17.45
Explanation: "Altogether" means we need to add the two amounts. Add the cents first: 90¢ + 55¢ = 145¢ = $1.45. Add the dollars:$ 12 + $4 =$ 16. Then add the dollar part of the cents: $16 +$ 1.45 = $17.45.
Common Mistake: Adding incorrectly, e.g., 90 + 55 = 145, but forgetting to carry over the $1.

4. A) $26.20

Working: $50.00 -$ 23.80 = $26.20
Explanation: "How much money does he have left" means we need to subtract the cost from the amount he had. $50.00 -$ 23.80. Since 0 cents minus 80 cents is not possible, we regroup 1 dollar as 100 cents. So we have $49.100 -$ 23.80 = $26.20.
Common Mistake: Subtracting incorrectly without regrouping: 50 - 23.80 = 27.20 (wrong).

5. A) $7

Explanation: In $17.65, the digit '7' is in the ones place (the dollars place). This means it represents 7 dollars, which is$ 7. The '1' represents $10, the '6' represents 60 cents ($ 0.60), and the '5' represents 5 cents ($0.05).
Common Mistake: Thinking the value of the digit is 7 cents ($0.07) because it's a decimal number.

6. C) $46.50

Working: (2 × $20) + (1 ×$ 5) + (3 × $0.50) =$ 40 + $5 +$ 1.50 = $46.50
Explanation: Calculate the total value of each type of note and coin. Two $20 notes =$ 40. One $5 note =$ 5. Three 50-cent coins = $1.50. Add them all:$ 40 + $5 +$ 1.50 = $46.50.
Common Mistake: Calculating the 50-cent coins as $0.50 each, but forgetting to multiply by 3.

7. B) $15.60

Working: $3.90 × 4 =$ 15.60
Explanation: "Cost of 4 such packets" means we multiply the cost of one packet by 4. $3.90 × 4. Multiply the cents: 90¢ × 4 = 360¢ =$ 3.60. Multiply the dollars: $3 × 4 =$ 12. Add them: $12 +$ 3.60 = $15.60.
Common Mistake: Adding instead of multiplying: $3.90 +$ 4 = $7.90 (wrong).

8. A) $21.50

Working: $50.00 -$ 28.50 = $21.50
Explanation: "Change" is the money returned when you pay more than the cost. Subtract the cost of the meal from the amount paid. $50.00 -$ 28.50 = $21.50.
Common Mistake: Adding instead of subtracting: $50 +$ 28.50 = $78.50 (wrong).

9. D) $10.55

Explanation: Compare the amounts. First, compare the dollars. $9.99 has 9 dollars, so it is the smallest. The other three have 10 dollars. Next, compare the cents.$ 10.05 has 5 cents, $10.50 has 50 cents, and$ 10.55 has 55 cents. 55 cents is the largest, so $10.55 is the largest amount.
Common Mistake: Thinking $10.50 is larger than$ 10.55 because 50 is a round number.

10. B) $0.35

Working: $1.20 -$ 0.85 = $0.35
Explanation: "How much more" means we need to find the difference, which is subtraction. $1.20 -$ 0.85. Since 20 cents minus 85 cents is not possible, we regroup 1 dollar as 100 cents. So we have $0.120 -$ 0.85 = $0.35.
Common Mistake: Adding instead of subtracting: $1.20 +$ 0.85 = $2.05 (wrong).

Section B: Short-Answer Questions (5 × 3 marks = 15 marks)

11. Answer: $7.30

Working: $22.90 -$ 15.60 = $7.30
Explanation: "How much more money does he need" means we find the difference between the cost and what he has. Subtract the amount he has from the cost of the book. $22.90 -$ 15.60 = $7.30.
Marking Scheme:
- 1 mark for correct operation (subtraction).
- 1 mark for correct working.
- 1 mark for correct final answer with dollar sign.

12. Answer: $29.75

Working:
- Cost of cookies: $18.50 -$ 7.25 = $11.25
- Total cost: $18.50 +$ 11.25 = $29.75
Explanation: First, find the cost of the cookies. The cookies cost $7.25 *less* than the chocolates, so we subtract:$ 18.50 - $7.25 =$ 11.25. Then, find the total cost by adding the cost of the chocolates and the cookies: $18.50 +$ 11.25 = $29.75.
Marking Scheme:
- 1 mark for finding the cost of the cookies.
- 1 mark for correct operation to find the total.
- 1 mark for correct final answer with dollar sign.

13. Answer: $35.60

Working:
- Total spent: $45.90 +$ 18.50 = $64.40
- Money left: $100.00 -$ 64.40 = $35.60
Explanation: First, find the total amount spent by adding the cost of the dress and the scarf: $45.90 +$ 18.50 = $64.40. Then, subtract the total spent from the amount she had:$ 100.00 - $64.40 =$ 35.60.
Marking Scheme:
- 1 mark for finding the total amount spent.
- 1 mark for correct operation to find the money left.
- 1 mark for correct final answer with dollar sign.

14. Answer: $6.60

Working:
- Cost of sandwich: $2.40 +$ 1.80 = $4.20
- Total cost: $2.40 +$ 4.20 = $6.60
Explanation: First, find the cost of the sandwich. The sandwich costs $1.80 *more* than the drink, so we add:$ 2.40 + $1.80 =$ 4.20. Then, find the total cost by adding the cost of the drink and the sandwich: $2.40 +$ 4.20 = $6.60.
Marking Scheme:
- 1 mark for finding the cost of the sandwich.
- 1 mark for correct operation to find the total.
- 1 mark for correct final answer with dollar sign.

15. Answer: $33.00

Working: $5.50 × 6 =$ 33.00
Explanation: "How much would he save after 6 weeks" means we multiply the amount saved each week by the number of weeks. $5.50 × 6. Multiply the cents: 50¢ × 6 = 300¢ =$ 3.00. Multiply the dollars: $5 × 6 =$ 30. Add them: $30 +$ 3.00 = $33.00.
Marking Scheme:
- 1 mark for correct operation (multiplication).
- 1 mark for correct working.
- 1 mark for correct final answer with dollar sign.

Section C: Problem-Solving Questions (5 × 1 mark = 5 marks)

16. Answer: $11.80

Working: (2 × $4.50) +$ 2.80 = $9.00 +$ 2.80 = $11.80
Explanation: First, find the cost of 2 ride tickets by multiplying: $4.50 × 2 =$ 9.00. Then, add the cost of 1 game ticket: $9.00 +$ 2.80 = $11.80.
Marking Scheme:
- 1 mark for correct final answer with dollar sign.

17. Answer: $8.20

Working: $20.00 -$ 11.80 = $8.20
Explanation: "Change" is the money returned. Subtract the total amount paid from the $20 note.$ 20.00 - $11.80 =$ 8.20.
Marking Scheme:
- 1 mark for correct final answer with dollar sign.

18. Answer: $5.40

Working: (3 × $1.20) + (2 ×$ 0.90) = $3.60 +$ 1.80 = $5.40
Explanation: First, find the cost of the apples: 3 × $1.20 =$ 3.60. Then, find the cost of the oranges: 2 × $0.90 =$ 1.80. Add them together: $3.60 +$ 1.80 = $5.40.
Marking Scheme:
- 1 mark for correct final answer with dollar sign.

19. Answer: $4.60

Working: $10.00 -$ 5.40 = $4.60
Explanation: "Change" is the money returned. Subtract the total amount spent from the $10 note.$ 10.00 - $5.40 =$ 4.60.
Marking Scheme:
- 1 mark for correct final answer with dollar sign.

20. Answer: 5 oranges

Working:
- Cost of apples: 5 × $1.20 =$ 6.00
- Cost of oranges: $10.50 -$ 6.00 = $4.50
- Number of oranges: $4.50 ÷$ 0.90 = 5
Explanation: First, find the cost of the apples: 5 × $1.20 =$ 6.00. Then, subtract the cost of the apples from the total spent to find the cost of the oranges: $10.50 -$ 6.00 = $4.50. Finally, divide the cost of the oranges by the price per orange to find the number of oranges:$ 4.50 ÷ $0.90 = 5.
Marking Scheme:
- 1 mark for correct final answer with unit.
