Answer:
The amount Carol must invest to reach her goal is $46,278.25
Explanation:
The PV formula given below would be very helpful in determining how much Carol should invest in CD account to reach $70,000 target value in 7 years with an interest rate of 6% compounded semiannually.
PV=FV*(1+r/2)^-n*2
FV is the target value of $70,000
r is the rate of interest which is 6%
n is the duration of investment in CD, which is 7 years
PV=$70,000*(1+6%/2)^-14=$ 46,278.25
the 14 is 7 years multiplied by 2 ,since interest is compounded twice a year
