Answer:
The principal needed for new addition is $ 53301.12
Step-by-step explanation:
Given as :
The amount needed for new addition = $75000
The Time period = 7 years
The rate of interest compounded annually = 5 %
Let The Amount invested = P
From compounded Method
Amount = Principal × [tex](1+\frac{Rate}{100})^{Time}[/tex]
Or, $ 75000 = P × [tex](1+\frac{5}{100})^{7}[/tex]
Or, $ 75000 = P × [tex](1.05)^{7}[/tex]
Or, $ 75000 = P × 1.4071
So, P = [tex]\frac{75000}{1.4071}[/tex] = $ 53301.115
Hence The principal needed for new addition is $ 53301.12 Answer
