Answer:
8.25%
Step-by-step explanation:
Orange, Inc. should calculate the MARR (minimum acceptable rate of return) for this project using the following:
Re = 12% (similar to Paste, Inc., so it can be considered the industry's average)
Rd = 6% x (1 - 25%) = 4.5%
MARR = (1/2 x 12%) + (1/2 x 4.5%) = 6% + 2.25% = 8.25%
This calculation is similar to calculating a company's WACC since you must determine the weighted cost of financing the project.
