Answer:
The principal which should be invested in account is $125,698.324
Step-by-step explanation:
Given as :
The monthly payment amount = $2500
The time period = 6 years = 6 × 12 = 72 months
So, The payment for 72 months = $2500 × 72 = $180,000
The rate of interest compounded monthly = 6%
The investment amount in account = P
Now, From compounded method
Amount = Principal × [tex](1+\frac{Rate}{12\times 100})^{12\times Time}[/tex]
$180,000 = P × [tex](1+\frac{6}{12\times 100})^{12\times 6}[/tex]
Or, $180,000 = P × [tex](1.005)^{72}[/tex]
Or, $180,000 = P × 1.432
∴ P = [tex]\frac{180,000}{1.432}[/tex] = $125,698.324
Hence The principal which should be invested in account is $125,698.324 . Answer
