Answer:
C. $9.04
Step-by-step explanation:
The net present value of a cash flow C in year n at some interest rate r is given by ...
NPV = C·(1 +r)^(-n)
Adding the values of the different cash flows at the different interest rates, we get the results shown in the attached table. The NPV goes up by $9.04 when the cost of capital goes down.

Neither WACC will cause this project to be rejected. If the WACC were to increase to 11.11%, then the project would have a zero return.
Let's recall that in a parallelogram:
1. The opposite sides are paralell
In our exercise. sides CZ and KG are paralell. And so do sides KC and GZ.
2. Those opposite sides are equal in length.
3. The opposites angles are equal. In our exercise, angle C and G are equal and so do angles K and Z.
4. That also mean that the angles at the top of the figure are supplementary. It means they add up to 180 degrees. We have the same situation with the two angles at the bottom of the parallelogram.
In our case then:
Now, we can find the measure of angles K and Z, as follows:
