All techniques with NPV profile$-$Mutually exclusive projects Projects A and $B,$ of equal risk, are alternatives for expanding Rosa Company's capacity. The firm's cost of capital is $14\%.$ The cash flows for each project are shown in the following table:

a$.$ Calculate each project's payback period.

b$.$ Calculate the net present value $($NPV$)$ for each project.

c$.$ Calculate the internal rate of return $($IRR$)$ for each project.

d$.$ Indicate which project you would recommend.

a$.$ The payback period of project $A$ is years. $($Round to two decimal places.$)$

The payback period of project $B$ is years. $($Round to two decimal places.$)$

b$.$ The NPV of project $A$ is $ $q,.($Round to the nearest cent.$)$

The NPV of project $B$ is $ $q,($Round to the nearest cent.$)$
