Mario Brothers, a game manufacturer, has a new idea for an adventure game. It can

either market the game as a traditional board game or as a PC game, but not both.

Consider the following cash flows of the two mutually exclusive projects. Assume the

discount rate for both projects is $9$ percent

a$.$ What is the payback period for each project? $($Do not round intermediate

calculations and round your answers to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

b$.$ What is the NPV for each project? $($Do not round intermediate calculations and

round your answers to $2$ decimal places, e$.$g$.,3216.)$

c$.$ What is the IRR for each project? $($Do not round intermediate calculations and enter

your answers as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

d$.$ What is the incremental IRR? $($Do not round intermediate calculations and enter your

answer as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
