please show steps to calculating each answer using functions on ti-84 calc. thanks

A company has a 12% WACC and is considering two mutually exclusive investments that cannot be repeated) with the following cash flows: 0 3 4 5 0 1 2 6 7 Project A -$300 -$387 -$ -$193 -$100 $600 $600 $850 -$180 Project B -$400 $132 $132 $132 $132 $132 $132 $0 a. What is each project's NPV? Negative values, if any, should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to the nearest cent. Project A: $ 200.41 Project B: $ 142.71 b. What is each project's IRR? Do not round intermediate calculations. Round your answers to two decimal places. Project A: 18.10 % Project B: 23.86 % c. What is each project's MIRR? (Hint: Consider Period 7 as the end of Project B's life.) Do not round intermediate calculations. Round your answers to two decimal places. Project A: 15.10 % Project B: % d. From your answers to parts a-c, which project would be selected? Project Av If the WACC was 18%, which project would be selected? Project Bv e. Construct NPV profiles for Projects A and B. If an amount is zero, enter O. Negative values, if any, should be indicated by a minus sign. Do not round intermediate calculations.
