I need to know what I'm doing wrong. Is there a formula to figure this out? What are the steps? The problem:

1.Wasp Corporation has a loan agreement that provides it with cash today, and the company must pay $25,000 one year from today, $15,000 two years from today, and $5,000 three years from today. Wasp agrees to pay 10% interest. The following are factors from a present value table:

Periods

Interest rate 10%

1

0.9091

2

0.8264

3

0.7513

What is the amount of cash that Wasp receives today?
