Answer:
The length of time = 12 years
Explanation:
The number of years the case would be determines the length time it takes the present value of annuity of 17,000 to equate the initial cost
Initial cost = A× (1- (1+r)^(-n)/r =
A- 17,000, r- 13%, n - ?
So we will need to work out the value of " n"
100,000 = 17,000 × 1- 1.13^(-n)/0.133
100,000/17,000 =1- 1.13^(-n)/0.13
5.88235 ×0.13 = 1- 1.13^(-n)
n = 12
The number of years is approximately 12 years
The length of time = 12 years
