Answer:
The equipment shall be financially attractive when we have annual cash inflow in excess of 132,686
Explanation:
Calculate the PVIFA ( Present value of interest factor annuity ) at r = 12 % and n = 4 years
= [ 1 - (1.12)-4 ] / 0.12 = 3.03734935
Minimum annual cash flow needed = Investment / PVIFA = 403,014 / 3.03734935
= 132686
The equipment shall be financially attractive when we have annual cash inflow in excess of 132,686
