Answer:
13.50%
Explanation:
Please find attached an image showing r and the cash flows
MIRR = (Future value of a firm's cash inflow / present value of the firm's cash outflow)^ (1/n) - 1
n = number of years
present value of the firm's cash outflow = $800
Future value of a firm's cash inflow
Future value of year 1's cash flow = 350 x (1.11^2) = $431.24
Future value of year 2's cash flow = 350 x (1.11^1) = $388.50
Future value of year 3's cash flow = $350
Add the future values together = 1169.74
MIRR = [(1169.74 / 800)^(1/3)] - 1 = 0.1350 = 13.50%
