Question

Solve the following problem:
Samuel has $58.23 in his bank account. He withdraws $39.78. How much is in his bank account now?(1 point)
$$

Answer 1

To find out how much is left in Samuel's bank account after he withdraws $39.78 from $58.23, we perform the following calculation:

\[
58.23 - 39.78
\]

Now, let's do the subtraction step-by-step:

1. Align the numbers by their decimal points:
```
58.23
- 39.78
```

2. Start subtracting from the rightmost digit:
- In the hundredths place: \( 3 - 8 \). Since 3 is less than 8, we need to borrow 1 from the tenths place (which makes it 1), so we have \( 13 - 8 = 5 \).
- In the tenths place: \( 1 - 7 \). Again, we need to borrow 1 from the units place (making it 7), leaving the tenths place as \( 11 - 7 = 4 \).
- In the units place: \( 7 - 9 \). We borrow from the next column (making it 4), and this gives us \( 17 - 9 = 8 \).
- Finally, in the tens place: \( 4 - 3 = 1 \).

Putting it all together, we have:

\[
58.23 - 39.78 = 18.45
\]

Thus, the amount left in Samuel's bank account is

\[
\boxed{18.45}
\]
