Answer:
A -$338,737
Step-by-step explanation:
initial outlay = -$892,000
cash flows year 1 - 4 = -$26,300
first we must determine the present value of the machine and its associated cash flows
PV = -$892,000 - $26,300/1.15 - $26,300/1.15² - $26,300/1.15³ - $26,300/1.15⁴ = -$967,085.93
equivalent annual cost (EAC) = (NPV x i) / [1 - (1 + i)⁻ⁿ] = (-$967,085.93 x 15%) / [1 - (1 + 15%)⁻⁴] = -$338,736.69 ≈ -$338,737
