-Note: PLEASE USE AN ACTUAL FORMULA for this ENGINEERING ECONOMY subject and not EXCEL PLEASE! This is my 3rd time posting this question and still receiving an excel answer! We are students not office staff! A firm that applies a 20% MARR on its investments is considering one of two 7-year engineering projects. Project 1 requires an initial investment of P4M, would generate an annual income of P2M, and would entail an annual cost of P0.4M, Project requires P7M, would generate an annual income of P3.7M for the first three years and P3M for the remaining four years, this project would incur annual disbursements of P0.8M. Indicate the better alternative using the incremental investment approach. (Ans. Project 2 is better; i,, =29.17%)
