Let’s solve each row step by step. We’ll add up the cost of items bought, then subtract that from the amount paid to find the payback (change).
Remember:
- 1 dime = 10¢
- 1 nickel = 5¢
---
Row 1:
Buy: $6 + $7 + $4 = $17 → but wait! The prices are in cents? Look at the symbols — they say “¢”, not “$”. So it’s 6¢, 7¢, 4¢.
Total buy: 6 + 7 + 4 =
17¢
Pay: 2 dimes = 2 × 10¢ =
20¢
Payback: 20 - 17 =
3¢
✔ Row 1: 3¢
---
Row 2:
Buy: 5¢ + 4¢ + 7¢ =
16¢
Pay: 1 dime + 2 nickels = 10¢ + (2 × 5¢) = 10 + 10 =
20¢
Payback: 20 - 16 =
4¢
✔ Row 2: 4¢
---
Row 3:
Buy: 2¢ + 4¢ + 11¢ =
17¢
Pay: 2 dimes = 20¢
Payback: 20 - 17 =
3¢
✔ Row 3: 3¢
---
Row 4:
Buy: 4¢ + 4¢ + 3¢ =
11¢
Pay: 1 dime + 1 nickel = 10 + 5 =
15¢
Payback: 15 - 11 =
4¢
✔ Row 4: 4¢
---
Row 5:
Buy: 4¢ + 9¢ + 6¢ =
19¢
Pay: 1 dime + 2 nickels = 10 + 10 =
20¢
Payback: 20 - 19 =
1¢
✔ Row 5: 1¢
---
Final Answer:
1. 3¢
2. 4¢
3. 3¢
4. 4¢
5. 1¢
