Looking for quick & Correct answer.

Two mutually exclusive alternatives are being considered. Alternative A has an initial cost of $100 and uniform annual benefit of $19.93. The useful life is 10 years, and the IRR is 15% Alternative B has an initial cost of $50 and uniform annual benefit of $11.93. The useful life is 10 years, and the IRR is 20% The MARR is 8%. Which of the following equation(s) will solve for the IRR that allows you to make a correct decision based on Rate of Return Analysis? O PW(A) = -100+ 19.93(P/A, i*, 10) PW(B) = -50+ 11.93(P/A, i*, 10) O PW(A) = -100+ 19.93(P/A, 8 %, 10) PW(B) = -50+ 11.93(P/A, 8%, 10) O PW-50-8(P/A, i*, 10) O PW 50+ 8(P/A, i*, 10) O PW-50 + 8(P/A, i*, 10) O PW = 50+ 8(P/A, 8%, 10) O PW(A) = 100 - 19.93(P/A, i*, 10) PW(B) = 50- 11.93(P/A, i*, 10) O PW(A) = 100 - 19.93(P/A, 8 %, 10) PW(B) = 50 - 11.93(P/A, 8%, 10) O Choose Alternative B, since the IRR is the largest. O Choose both Alternative A and B, since IRR is greater than the MARR.
