EXERCISE 6-10 (10–15 minutes) (a) The number of interest periods is calculated by first dividing the future value of \$1,000,000 by \$148,644, which is 6.72748—the value \$1.00 would accumulate to at 10% for the unknown number of interest periods. The factor 6.72748 or its approximate is then located in the Future Value of 1 Table by reading down the 10% column to the 20-period line; thus, 20 is the unknown number of years Mark must wait to become a millionaire. (b) The unknown interest rate is calculated by first dividing the future value of \$1,000,000 by the present investment of \$239,392, which is 4.17725— the amount \$1.00 would accumulate to in 15 years at an unknown interest rate. The factor or its approximate is then located in the Future Value of 1 Table by reading across the 15- period line to the 10% column; thus, 10% is the interest rate Elvira must earn on her investment to become a millionaire.
