Given formula analysis: We are given the formula for compound interest: P=500(1.035)n. To find the annual interest rate, we need to look at the base of the exponent, which is 1.035 in this case. This base represents the growth factor for one year, which includes the original amount plus the interest rate. To find the interest rate, we subtract 1 from the growth factor.
Calculate interest rate: Calculate the interest rate by subtracting 1 from the growth factor:Interest rate = 1.035−1Interest rate = 0.035
Convert to percent: Convert the interest rate from decimal form to percent form by multiplying by 100:Interest rate in percent=0.035×100Interest rate in percent=3.5%
