Let’s solve each problem one by one. We’ll add or subtract the numbers carefully, making sure to line up the decimal points and handle borrowing or carrying when needed.

Problem 1: $98.69 + $27.71
Add cents first:
69 + 71 = 140 → that’s $1.40 → write down .40, carry over $1
Now dollars:
98 + 27 = 125, plus the carried $1 = 126
Total:
$126.40
✔ Matches given answer.
---
Problem 2: $31.80 - $20.77
Subtract cents:
80 - 77 = 3 → so .03
Dollars:
31 - 20 = 11
Total:
$11.03
✔ Matches given answer.
---
Problem 3: $86.93 + $74.50
Cents: 93 + 50 = 143 → $1.43 → write .43, carry $1
Dollars: 86 + 74 = 160, plus $1 = 161
Total:
$161.43
✔ Matches given answer.
---
Problem 4: $47.29 - $30.79
Cents: 29 - 79 → can’t do! Borrow $1 from 47 → becomes 46, and 29 becomes 129
129 - 79 = 50 → .50
Dollars: 46 - 30 = 16
Total:
$16.50
✔ Matches given answer.
---
Problem 5: $52.16 - $42.00
Easy! Just subtract:
52.16 - 42.00 = (52 - 42) + (.16 - .00) = 10 + .16 =
$10.16
✔ Matches given answer.
---
Problem 6: $31.97 - $1.50
Cents: 97 - 50 = 47 → .47
Dollars: 31 - 1 = 30
Total:
$30.47
✔ Matches given answer.
---
Problem 7: $99.35 + $94.92
Cents: 35 + 92 = 127 → $1.27 → write .27, carry $1
Dollars: 99 + 94 = 193, plus $1 = 194
Total:
$194.27
✔ Matches given answer.
---
Problem 8: $6.56 + $52.48
Cents: 56 + 48 = 104 → $1.04 → write .04, carry $1
Dollars: 6 + 52 = 58, plus $1 = 59
Total:
$59.04
✔ Matches given answer.
---
Problem 9: $53.26 - $48.73
Cents: 26 - 73 → can’t do! Borrow $1 → 53 becomes 52, 26 becomes 126
126 - 73 = 53 → .53
Dollars: 52 - 48 = 4
Total:
$4.53
✔ Matches given answer.
---
Problem 10: $66.36 - $1.87
Cents: 36 - 87 → borrow $1 → 66 becomes 65, 36 becomes 136
136 - 87 = 49 → .49
Dollars: 65 - 1 = 64
Total:
$64.49
✔ Matches given answer.
---
Problem 11: $34.54 + $0.71
Cents: 54 + 71 = 125 → $1.25 → write .25, carry $1
Dollars: 34 + 0 = 34, plus $1 = 35
Total:
$35.25
✔ Matches given answer.
---
Problem 12: $39.97 + $0.79
Cents: 97 + 79 = 176 → $1.76 → write .76, carry $1
Dollars: 39 + 0 = 39, plus $1 = 40
Total:
$40.76
✔ Matches given answer.
