### Understanding Interest on Credit Card Debt

**Problem Statement:**

Jamie wants a new smart TV/sound system that costs $1,250. He does not have that much in cash to purchase it, so he uses a credit card with 18% annual interest. He puts $250 down, but he only pays the interest each month on that credit card debt. About how much will he pay in interest over 4 years?

**Multiple Choice Answers:**

- **A:** $1000
- **B:** $720
- **C:** $500
- **D:** $800

#### Solution Explanation:

To determine how much Jamie will pay in interest over four years, we'll follow these steps:

1. **Calculate the remaining principal**: After making a $250 down payment on the $1,250 TV/sound system, Jamie has $1,250 - $250 = $1,000 left to pay.

2. **Understand the interest rate**:
   - Annual interest rate = 18%
   - Monthly interest rate = 18% / 12 months = 1.5%

3. **Calculate monthly interest**: 
    - Since Jamie is only paying the interest each month, interest paid monthly = 1,000 * 1.5% = $15

4. **Calculate total interest over 4 years**:
   - Interest per year = $15 * 12 months = $180
   - Interest over 4 years = $180 * 4 = $720

Thus, over four years, Jamie will pay approximately **$720** in interest on the credit card debt.

**Correct Answer: B ($720)**
