Excel Activity: Capital Budgeting Tools Gardial Fisheries is considering two mutually exclusive investments. The projects' expected net cash flows are as follows:

Expected Net Cash Flows
Year	Project A	Project B
0	-$420	-$620
1	-410	175
2	-280	175
3	-140	175
4	840	175
5	840	175
6	828	175
7	-280	175

Do not round intermediate calculations.

At a cost of capital of 8%, what is the discounted payback period for these two projects? Round your answers to two decimal places.

Discounted payback period (Project A): _________ years

Discounted payback period (Project B): _________ years

Please provide the excel formula for the the answer number too, I would love to understand them, please tell me if some element necessary to answer the questions is missing. Thank you very much.
