Use the appropriate formula to find the future value (in $) of $700 deposited at the beginning of every six months, for 17 years if a bank pays 8% interest, compounded semiannually. (Round your answers to the nearest cent.)
Q. Use the appropriate formula to find the future value (in $) of $700 deposited at the beginning of every six months, for 17 years if a bank pays 8% interest, compounded semiannually. (Round your answers to the nearest cent.)
Identify Formula: Identify the formula for the future value of an annuity due to regular deposits and compound interest.The formula for the future value of an annuity due is:FV=P×(r(1+r)n−1)×(1+r)where:- FV is the future value of the annuity.- P is the payment amount per period.- r is the interest rate per period.- n is the total number of periods.
Determine Values: Determine the values of P, r, and n for this problem. P = $700 (the deposit made every six months)The annual interest rate is 8%, so the semiannual rate is 28%=4% or r=0.04.There are 17 years with two periods per year, so n=17×2=34 periods.
Substitute and Calculate: Substitute the values into the formula and calculate the future value.FV=700×(0.04(1+0.04)34−1)×(1+0.04)
Calculate Future Value: Calculate the future value using the values provided.First, calculate (1+r)n:(1+0.04)34Use a calculator to find this value.
