Final answer:
To calculate the EAC, use the formula EAC = C x PVAF. Substitute the values into the formulas to find the EAC.
Step-by-step explanation:
To calculate the equivalent annual cost (EAC), we need to find the present value of the net cash flows over the project's life. The formula for calculating the present value of an annuity is:
EAC = C x PVAF
Where:
C is the cash flow per period
PVAF is the present value annuity factor
In this case, the cash flow per period is the annual operating cash flow, which is -$46,720. The present value annuity factor can be calculated using the formula:
PVAF = (1 - (1 / (1+r)^n)) / r
Where:
r is the required return rate, which is 15% or 0.15
n is the number of periods, which is 4 years
By substituting the values into the formulas, we can calculate the EAC.
