1. **State the problem:** Joseph loaned 3750 to Kelsey at a simple interest rate of 3.68% per annum for 2 years and 8 months. We need to calculate the interest charged at the end of the term.
2. **Formula for simple interest:**
$$I = P \times r \times t$$
where:
- $I$ is the interest
- $P$ is the principal amount
- $r$ is the annual interest rate (in decimal)
- $t$ is the time in years
3. **Convert the interest rate to decimal:**
$$r = \frac{3.68}{100} = 0.0368$$
4. **Convert the time to years:**
2 years and 8 months = 2 + \frac{8}{12} = 2 + \frac{2}{3} = \frac{6}{3} + \frac{2}{3} = \frac{8}{3} \text{ years}$$
5. **Calculate the interest:**
$$I = 3750 \times 0.0368 \times \frac{8}{3}$$
6. **Intermediate calculation:**
$$I = 3750 \times 0.0368 \times 2.6667$$
7. **Multiply step-by-step:**
$$3750 \times 0.0368 = 138$$
8. **Final interest:**
$$I = 138 \times 2.6667 = 368$$
**Answer:** The interest charged at the end of the term is $368$.
