P( 1 + r yt, ompounded semiannually, A (t) rn 8. If $4500 is invested at an interest rate of 2.5% per year, c find the value of the investment after six years.
Solution
P=4500, r=2.5%=2.5*(1/100)=0.025
compounded semi annually => n=2
sixyears => t=6
value of investment ,A= 4500*(1+(0.025/2))2*6
value of investment ,A= 4500*(1+0.0125)12
value of investment ,A= 4500*(1.0125)12
value of investment ,A= 4500*1.161
