Simple Interest 1Da321
1. **State the problem:** We need to find the principal amount that will earn 176.42 in interest at an annual simple interest rate of 4.75% over 8 months.
2. **Formula for simple interest:**
$$I = P \times r \times t$$
where $I$ is the interest earned, $P$ is the principal, $r$ is the annual interest rate (in decimal), and $t$ is the time in years.
3. **Convert given values:**
- Interest $I = 176.42$
- Rate $r = 4.75\% = 0.0475$
- Time $t = \frac{8}{12} = \frac{2}{3}$ years
4. **Rearrange formula to find principal:**
$$P = \frac{I}{r \times t}$$
5. **Substitute values:**
$$P = \frac{176.42}{0.0475 \times \frac{2}{3}} = \frac{176.42}{0.0316667}$$
6. **Calculate principal:**
$$P \approx 5568.94$$
**Answer:** The principal amount is approximately 5568.94.
