Let’s solve each problem one by one. We’ll add or subtract the money amounts as shown, making sure to line up the decimal points and handle borrowing or carrying when needed.
---
Problem 1: $24.80 - $12.65
Start from the right:
- 0 - 5 → can’t do, borrow from 8 → becomes 10 - 5 = 5
- Now 7 (after borrow) - 6 = 1
- 4 - 2 = 2
- 2 - 1 = 1
→
$12.15
---
Problem 2: $97.59 - $91.33
- 9 - 3 = 6
- 5 - 3 = 2
- 7 - 1 = 6
- 9 - 9 = 0
→
$6.26
---
Problem 3: $81.05 + $68.02
- 5 + 2 = 7
- 0 + 0 = 0
- 1 + 8 = 9
- 8 + 6 = 14 → write 4, carry 1 → total 149.07? Wait:
Actually:
81.05
+ 68.02
= (81 + 68) + (0.05 + 0.02) = 149 + 0.07 →
$149.07
---
Problem 4: $12.27 + $71.53
- 7 + 3 = 10 → write 0, carry 1
- 2 + 5 + 1 = 8
- 2 + 1 = 3
- 1 + 7 = 8
→
$83.80
---
Problem 5: $70.30 + $88.03
- 0 + 3 = 3
- 3 + 0 = 3
- 0 + 8 = 8
- 7 + 8 = 15 → write 5, carry 1 → 158.33
→
$158.33
---
Problem 6: $59.16 - $18.06
- 6 - 6 = 0
- 1 - 0 = 1
- 9 - 8 = 1
- 5 - 1 = 4
→
$41.10
---
Problem 7: $76.91 - $48.72
- 1 - 2 → borrow → 11 - 2 = 9
- 8 (after borrow) - 7 = 1
- 6 - 8 → borrow → 16 - 8 = 8
- 6 (after borrow) - 4 = 2
→
$28.19
---
Problem 8: $69.87 - $58.02
- 7 - 2 = 5
- 8 - 0 = 8
- 9 - 8 = 1
- 6 - 5 = 1
→
$11.85
---
Problem 9: $60.74 + $29.22
- 4 + 2 = 6
- 7 + 2 = 9
- 0 + 9 = 9
- 6 + 2 = 8
→
$89.96
---
Problem 10: $34.56 + $18.74
- 6 + 4 = 10 → write 0, carry 1
- 5 + 7 + 1 = 13 → write 3, carry 1
- 4 + 8 + 1 = 13 → write 3, carry 1
- 3 + 1 + 1 = 5
→
$53.30
---
Problem 11: $69.11 - $62.51
- 1 - 1 = 0
- 1 - 5 → borrow → 11 - 5 = 6
- 8 (after borrow) - 2 = 6
- 6 - 6 = 0
→
$6.60
---
Problem 12: $57.51 + $86.65
- 1 + 5 = 6
- 5 + 6 = 11 → write 1, carry 1
- 7 + 6 + 1 = 14 → write 4, carry 1
- 5 + 8 + 1 = 14
→
$144.16
---
Problem 13: $83.65 - $52.96
- 5 - 6 → borrow → 15 - 6 = 9
- 5 (after borrow) - 9 → borrow → 15 - 9 = 6
- 2 (after borrow) - 2 = 0
- 8 - 5 = 3
→
$30.69
---
Problem 14: $84.64 + $80.67
- 4 + 7 = 11 → write 1, carry 1
- 6 + 6 + 1 = 13 → write 3, carry 1
- 4 + 0 + 1 = 5
- 8 + 8 = 16
→
$165.31
---
Problem 15: $38.93 + $44.39
- 3 + 9 = 12 → write 2, carry 1
- 9 + 3 + 1 = 13 → write 3, carry 1
- 8 + 4 + 1 = 13 → write 3, carry 1
- 3 + 4 + 1 = 8
→
$83.32
---
Problem 16: $69.95 - $65.15
- 5 - 5 = 0
- 9 - 1 = 8
- 9 - 5 = 4
- 6 - 6 = 0
→
$4.80
---
Problem 17: $32.25 - $26.49
- 5 - 9 → borrow → 15 - 9 = 6
- 1 (after borrow) - 4 → borrow → 11 - 4 = 7
- 1 (after borrow) - 6 → borrow → 11 - 6 = 5
- 2 (after borrow) - 2 = 0
→
$5.76
---
Problem 18: $32.04 - $25.52
- 4 - 2 = 2
- 0 - 5 → borrow → 10 - 5 = 5
- 1 (after borrow) - 5 → borrow → 11 - 5 = 6
- 2 (after borrow) - 2 = 0
→
$6.52
