Sure! Let’s solve each money subtraction problem step by step. We’ll subtract the bottom amount from the top amount in each column.

Column 1:
1. $2.30 - $1.34
Align decimals:
```
2.30
- 1.34
------
```
Start from the right:
-
Hundredths place: 0 - 4 → Can’t do, so borrow 1 from tenths place.
- Tenths becomes 2, hundredths becomes 10 → 10 - 4 = 6
-
Tenths place: 2 - 3 → Can’t do, borrow 1 from dollars.
- Dollars become 1, tenths become 12 → 12 - 3 = 9
-
Dollars place: 1 - 1 = 0
✔ Answer:
$0.96
---
2. $1.09 - $0.87
```
1.09
- 0.87
------
```
- Hundredths: 9 - 7 = 2
- Tenths: 0 - 8 → borrow → 10 - 8 = 2 (dollars become 0)
- Dollars: 0 - 0 = 0
✔ Answer:
$0.22

3. $10.53 - $10.00
Easy — just subtract:
```
10.53
- 10.00
-------
0.53
```
✔ Answer:
$0.53
---
4. $38.00 - $20.73
```
38.00
- 20.73
-------
```
- Hundredths: 0 - 3 → borrow → 10 - 3 = 7 (tenths now 9)
- Tenths: 9 - 7 = 2
- Dollars: 38 - 20 = 18? Wait — we borrowed from 8 → actually 37.99 + 0.01, but easier:
Think: 38.00 - 20.73 = ?
You can also think:
38.00 - 20.00 = 18.00
Then 18.00 - 0.73 = 17.27
✔ Answer:
$17.27

Column 2:
1. $6.00 - $2.29
```
6.00
- 2.29
------
```
- Hundredths: 0 - 9 → borrow → 10 - 9 = 1 (tenths now 9)
- Tenths: 9 - 2 = 7
- Dollars: 5 - 2 = 3 (since we borrowed 1)
✔ Answer:
$3.71

2. $8.20 - $3.39
```
8.20
- 3.39
------
```
- Hundredths: 0 - 9 → borrow → 10 - 9 = 1 (tenths now 1)
- Tenths: 1 - 3 → borrow → 11 - 3 = 8 (dollars now 7)
- Dollars: 7 - 3 = 4
✔ Answer:
$4.81

3. $5.25 - $3.75
```
5.25
- 3.75

```
- Hundredths: 5 - 5 = 0

- Dollars: 4 - 3 = 1
✔ Answer:
$1.50
