$14.20
B.
$19.60
C.
$15.70
D.
$15.40

Answer 1

To determine how much money Mike has left at the end of the school week, we will first calculate his total expenses.

1. **Calculate the cost of school lunches from Monday to Thursday:**
- Cost of one school lunch: $1.50
- Number of lunches: 4 (Monday through Thursday)
- Total cost for school lunches:
\[
4 \text{ lunches} \times 1.50 \text{ per lunch} = 6.00
\]

2. **Calculate the cost of pizza on Friday:**
- Cost of one slice of pizza: $1.20
- Number of slices: 4
- Total cost for pizza:
\[
4 \text{ slices} \times 1.20 \text{ per slice} = 4.80
\]

3. **Calculate the total expenses for the week:**
- Total expenses = Cost of school lunches + Cost of pizza
\[
6.00 + 4.80 = 10.80
\]

4. **Subtract total expenses from the amount given by mom:**
- Initial amount: $25.00
- Amount spent: $10.80
- Amount left:
\[
25.00 - 10.80 = 14.20
\]

Therefore, the amount of money Mike has left at the end of the school week is **$14.20**.

The correct answer is **A. $14.20**.
