What is the annual rate of interest if 265 is earned in four months on an investment of 15 000?

To find the annual rate of interest, first determine the interest earned per year. Since $265 is earned in four months, the annual interest would be (265 \times 3 = 795) dollars. Next, divide the annual interest by the principal amount and multiply by 100 to get the percentage: (\frac{795}{15000} \times 100 \approx 5.3%). Therefore, the annual rate of interest is approximately 5.3%.
