Answer:
Explanation:
Principal Payment $160
Her Employee help to add $80
Total principal is (160+80)= $240
At a rate of 0.45
For a time of 35years
We will compound her amount
Using compound interest formula
A=P(1+r/n)^nt
Where,
P = principal amount = $240
r = annual rate of interest =0.45
t = number of years the amount invested =35years
A = amount of money accumulated after n years, including interest.
n = number of times the interest is compounded per year=12months
Therefore,
A=P(1+r/n)^nt
A=240(1+0.43/12)^35×12
A=240(1+0.03583)^420
A=240(1.03583)^420
A=240×2.641
A=$633.814
The amount is approximately $633.814
