Answer:
The student should have in his account now the sum of $ 54,365
Explanation:
In arriving at the amount above,I used the present value formula,which is:
PV=FV/(1+r)^n
FV=future value=$15000 at the beginning of each of the four years
r[=rate=7%
n=number for each payment
The table below showed the detailed calculation
Year Cash flows FV/(1+r)^n
0 15000 15000
1 15000 14,019
2 15000 13,102
3 15000 12,244
Total 54,365
Please note that the beginning of year of year 1 is the same as year 0 and so on.
