A company whose MARR is 8%, is evaluating two new processes for improving its manufacturing efficiency. Using the cash flow estimates shown below, a correct equation for an incremental rate of return analysis is: 0 = - 10,000 + 3000(P/A. 8%, 3) + 1000(P/F, 8%, 3) 0 = - 40.000(A/P, 8%, 3) -15,000 + 5000(A/F, 8%, 3) 0 = - 50,000(A/p, 8%, 3) - 12,000 + 6000(A/F, 8%, 3) 0 = -10,000 3000(P/, 8%, 3) + 1000(P/F, 8%, 3)
