1. Use the simple interest formula, I = Prt to find the unknown value. i) I = ?, P = $800, r = 10%, t = 6 years ii) I = $37.92, P = ?, r = 5%, t = 8 months
2. Calculate the rate per compounding period, i, for each of the following. i) 9% per annum, compounded monthly ii) 6% per annum, compounded quarterly
3. Calculate the total number of compounding periods, n, for each of the following. i) Compounded semi-annually for 8 years ii) Compounded monthly for 6 years
