Answer:
Yes the company should you pursue the project.
Explanation:
This problem requires us to tell whether we should pursue the project or not. The IRR of the project is given in the question and WAAC is required to be calculated. The company should accept the project if IRR (10%) is greater than or equal to company's WAAC.
So let calculate waac first.
WAAC = 80%* 8.5% (100% -21%) + 20% * 11%
= 5.4% + 2.2 %
= 7.6%
based on above mentioned rule the company should pursue the project.
