Question

Sporting goods charges .85 percent interest per month. what rate of interest are its credit customers actually paying?

Answer 1

To answer this item, we assume that the interest rate is simple, such that the yearly rate was only divided by 12 months in order to determine the rate per month. Hence, to answer this item, we simply have to multiply the given percent by 12.

                          rate of interest/year = (12)(0.85%) = 10.2%

Therefore, the answer is 10.2%.
