A company has a 12% WACC and is considering two mutually exclusive investments (that cannot be repeated) with the following cash flows:

0 1 2 3 4 5 6 7

Project A -$300 -$387 -$193 -$100 $600 $600 $850 -$180

Project B -$405 $135 $135 $135 $135 $135 $135 $0

d. If the WACC was 18%, which project would be selected?

e. Construct NPV profiles for Projects A and B. If an amount is zero, enter 0. Negative values, if any, should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to the nearest cent.

f. Calculate the crossover rate where the two projects' NPVs are equal. Do not round intermediate calculations. Round your answer to two decimal places.

g. What is each project's MIRR at a WACC of 18%? Do not round intermediate calculations. Round your answers to two decimal places.

Please explain the whole process of using excel to calculate in detail, especially the excel formula to calculate the answer of e and g. Thanks.
