Question

You put $500 in a savings account. The account earns $15.75 simple interest in 6 months. What is the annual interest rate? Show work step by step.

1 Answer

  • So in 6 months (1/2yr) you earned $15.75 interest, if we double that we find the total interest you would gain for that year, 15.75x2= $31.5 total interest for that year.

    To find the annual rate divide the interest gained by the amount deposited, 31.5/500 = 0.063% p.a.
