Answer Key: Primary 3 Mathematics Quiz - Money

Total Marks: 40

Section A: Multiple-Choice Questions (Questions 1 to 5)

Each question carries 2 marks.

1. C) $39

Working: (2 × $10) + (3 ×$ 5) + (4 × $1) =$ 20 + $15 +$ 4 = $39
Explanation: Count the value of each type of note or coin first, then add them together. Ten-dollar notes: 2 × $10 =$ 20. Five-dollar notes: 3 × $5 =$ 15. One-dollar coins: 4 × $1 =$ 4. Total = $20 +$ 15 + $4 =$ 39.
Common Mistake: Students may forget to multiply the number of notes by their value.

2. A) $6.60

Working: $15.50 -$ 8.90 = $6.60
Explanation: "How much money does she have left" means we need to subtract the cost of the book from the amount she had. Align the decimal points and subtract: $15.50 -$ 8.90 = $6.60.
Marking Note: Award 1 mark for correct method, 1 mark for correct answer.

3. B) $8.05

Explanation: Eight dollars and five cents means $8 and$ 0.05. In decimal notation, we write the dollars, then a decimal point, then the cents. Since 5 cents is less than 10 cents, we write it as .05. So the correct answer is $8.05.
Common Mistake: Students often write $8.5 or$ 8.50, but $8.5 means$ 8 and 50 cents, and $8.50 also means$ 8 and 50 cents. Only $8.05 means$ 8 and 5 cents.

4. B) $4.00

Working: $2.45 +$ 1.55 = $4.00
Explanation: Add the two prices together. $2.45 +$ 1.55 = $4.00. Notice that 45 cents + 55 cents = 100 cents, which is exactly$ 1. So $2 +$ 1 + $1 =$ 4.00.
Marking Note: Award 1 mark for correct method, 1 mark for correct answer.

5. B) No, he is short by $0.30.

Working: Total cost = $12.90 +$ 6.80 = $19.70. He has$ 20. $20 -$ 19.70 = $0.30. He has enough money and will have$ 0.30 left.
Explanation: First, find the total cost of both items. Then, subtract the total cost from the money he has. Since $20 -$ 19.70 = $0.30, he has enough money and will get$ 0.30 change. The answer should be "Yes, he has $0.30 left."
Correction: The correct answer is D) Yes, he has $0.30 left. The initial answer key had an error. The correct answer is D.

Section B: Short-Answer Questions (Questions 6 to 15)

Each question carries 2 marks.

6. $5.75

Working:
```
$3.45
+ $2.30
--------
$5.75
```
Explanation: Align the decimal points and add column by column. 45 cents + 30 cents = 75 cents. $3 +$ 2 = $5. So the total is$ 5.75.
Marking Note: Award 1 mark for correct working, 1 mark for correct answer.

7. $7.20

Working:
```
$15.00
- $7.80
--------
$7.20
```
Explanation: Align the decimal points. Since 0 cents - 80 cents is not possible, we need to regroup. Borrow 1 dollar (100 cents) from the $15, making it$ 14 and 100 cents. Then 100 cents - 80 cents = 20 cents. $14 -$ 7 = $7. So the answer is$ 7.20.
Marking Note: Award 1 mark for correct working (showing regrouping), 1 mark for correct answer.

8. $6.75

Working: $4.50 +$ 2.25 = $6.75
Explanation: Add the cost of the sandwich and the drink. 50 cents + 25 cents = 75 cents. $4 +$ 2 = $6. Total is$ 6.75.
Marking Note: Award 1 mark for correct method, 1 mark for correct answer.

9. $26.40

Working: $50.00 -$ 23.60 = $26.40
Explanation: "How much money does she have left" means subtraction. $50.00 -$ 23.60 = $26.40. Regroup: 100 cents - 60 cents = 40 cents.$ 49 - $23 =$ 26.
Marking Note: Award 1 mark for correct method, 1 mark for correct answer.

10. $0.35

Working: $1.20 -$ 0.85 = $0.35
Explanation: "How much more" means we find the difference by subtracting. $1.20 -$ 0.85 = $0.35. Regroup: 120 cents - 85 cents = 35 cents.
Marking Note: Award 1 mark for correct method, 1 mark for correct answer.

11. $11.00

Working: $6.15 +$ 4.85 = $11.00
Explanation: Add the two amounts. 15 cents + 85 cents = 100 cents = $1.00.$ 6 + $4 +$ 1 = $11. So the sum is$ 11.00.
Marking Note: Award 1 mark for correct method, 1 mark for correct answer.

12. $3.60

Working: $12.50 -$ 8.90 = $3.60
Explanation: "Difference in price" means subtract the smaller price from the larger price. $12.50 -$ 8.90 = $3.60. Regroup: 150 cents - 90 cents = 60 cents.$ 11 - $8 =$ 3.
Marking Note: Award 1 mark for correct method, 1 mark for correct answer.

13. $4.00

Working: Total spent = $2.40 +$ 3.60 = $6.00. Money left =$ 10.00 - $6.00 =$ 4.00.
Explanation: First, find the total amount spent. Then, subtract the total spent from the amount he had. $2.40 +$ 3.60 = $6.00.$ 10.00 - $6.00 =$ 4.00.
Marking Note: Award 1 mark for correct method, 1 mark for correct answer.

14. $12.80

Working: Cost of 2 notebooks = 2 × $3.45 =$ 6.90. Total cost = $5.90 +$ 6.90 = $12.80.
Explanation: First, find the cost of 2 notebooks by multiplying. Then, add the cost of the markers. 2 × $3.45 =$ 6.90. $5.90 +$ 6.90 = $12.80.
Marking Note: Award 1 mark for correct method, 1 mark for correct answer.

15. $28.30

Working: $12.80 +$ 15.50 = $28.30
Explanation: "How much did she save in total" means we add the two amounts. 80 cents + 50 cents = 130 cents = $1.30.$ 12 + $15 +$ 1 = $28. Total is$ 28.30.
Marking Note: Award 1 mark for correct method, 1 mark for correct answer.

Section C: Problem-Solving Questions (Questions 16 to 20)

Each question carries 4 marks.

16. $5.00

Working:
- Cost of 4 games = 4 × $2.50 =$ 10.00
- Money left = $15.00 -$ 10.00 = $5.00
Explanation: First, find the total cost of playing 4 games by multiplying the cost per game by the number of games. Then, subtract the total cost from the amount he had. 4 × $2.50 =$ 10.00. $15.00 -$ 10.00 = $5.00.
Marking Scheme:
- 1 mark for correct method to find total cost of games
- 1 mark for correct calculation of total cost
- 1 mark for correct method to find money left

- Total cost = $9.60 +$ 5.90 = $15.50
- Change = $50.00 -$ 15.50 = $34.50
Explanation: This is a multi-step problem. First, find the cost of the rice. Then, find the total cost of all items. Finally, subtract the total cost from the amount paid to find the change. 3 × $3.20 =$ 9.60. $9.60 +$ 5.90 = $15.50.$ 50.00 - $15.50 =$ 34.50.
Marking Scheme:
- 1 mark for correct method to find cost of rice

- Change = $10.00 -$ 6.40 = $3.60
Explanation: First, find the cost of the apples and oranges separately. Then, add them to find the total cost. Finally, subtract the total cost from the $10 note to find the change. 5 ×$ 0.80 = $4.00. 4 ×$ 0.60 = $2.40.$ 4.00 + $2.40 =$ 6.40. $10.00 -$ 6.40 = $3.60.
Marking Scheme:
