Final answer:
The modified internal rate of return (MIRR) for project S is 9.67%.
Step-by-step explanation:
The modified IRR (MIRR) for project S can be calculated by finding the discount rate that equates the present value of all cash inflows to the present value of all outflows. To calculate the MIRR, you need to find the future value (FV) of cash inflows and future value (FV) of cash outflows:
FV of cash inflows = $550 * (1 + 7.5%)^1 + $600 * (1 + 7.5%)^2 + $100 * (1 + 7.5%)^3 + $100 * (1 + 7.5%)^4 = $1,277.57
FV of cash outflows = $1,100 * (1 + 7.5%)^0 + $650 * (1 + 7.5%)^1 + $725 * (1 + 7.5%)^2 + $800 * (1 + 7.5%)^3 + $1,400 * (1 + 7.5%)^4 = $3,303.14
Then, calculate the MIRR using the formula:
MIRR = (FV of cash inflows / PV of cash outflows)^(1/n) - 1
Where n is the number of cash inflows/outflows. In this case, n = 5.
Calculating MIRR: MIRR = ($1,277.57 / $3,303.14)^(1/5) - 1 = 9.67%
