Answer:
C(5)= $13,172.05
Step-by-step explanation:
To calculate C(t), we need to divide the formula into two equations:
C(t) =b(t) +h(t)
b(t)= PV*(1+i)^n
n= number of months
i= monthly interest rate
PV= initial investment
h(t)= montlhy deposit* number of months
Now, for C(5); I assume its 5 years:
i= 0.036/12= 0.003
n= 5*12= 60
C(5)= 9,000*(1.003^60) + 40*60
C(5)= $13,172.05
