Answer 1

To calculate the total amount charged to your debit card, let's break it down step-by-step.

1. **Cost of gasoline:**
- 10.75 gallons at $3.60/gallon:
\[
\text{Cost of gasoline} = 10.75 \times 3.60 = 38.70
\]

2. **Cost of cookie:**
- $1.25

3. **Cost of windshield wiper fluid:**
- $4.97

4. **Total cost before tax (gasoline + cookie + windshield wiper fluid):**
\[
\text{Total cost before tax} = 38.70 + 1.25 + 4.97 = 44.92
\]

5. **Tax on cookie (food tax of 4%):**
- Only the cookie is taxable, so:
\[
\text{Tax on cookie} = 1.25 \times 0.04 = 0.05
\]

6. **Total amount after including tax:**
\[
\text{Total amount} = 44.92 + 0.05 = 44.97
\]

7. **Amount paid in cash:**
- You gave the clerk $20.00.

8. **Amount charged to debit card:**
\[
\text{Amount charged to debit card} = \text{Total amount} - \text{Amount paid in cash}
\]
\[
\text{Amount charged to debit card} = 44.97 - 20.00 = 24.97
\]

Thus, the amount charged to your debit card is **$24.97**.
