Answer:
Total= $14,572.964
Step-by-step explanation:
Giving the following information:
Spendings:
Year 3= $5,100
Year 5= $9,500
Year 7= $6,500
Interest rate= 7.6 compunded annually.
We need to determine the initial investment to cover for 3 spendings.
We will calculate the present value of each payment, and sum them to determine the initial investment:
PV= FV/(1+i)^n
Year 3= 5,100/1.076^3= $4,093.864
Year 5= 9,500/1.076^5= $6,586.61
Year 7= 6,500/1.076^7= $3,892.49
Total= $14,572.964
TO prove it:
FV= PV*(1+i)^n
FV= (14,573*1.076^3) - 5,100= $13,054.56
FV= (13,054.56*1.076^2) - 9,500= $5,614.26
FV= (5,614.26*1.076^2) - 6,500= 0
