Suppose you are looking at the following possible cash flows:

Year 1 CF= $200

Year 2 CF= 0

Year 3 CF= $420

Year 4 CF= $500

Year 5 CF= $500

A) What is the present value of these cash flows?

B) What is the value of these cash flows at the end of Year 4?

C)What is the value of these cash flows at the end of Year 6?

Please show work, so I can better understand how to do these! Thank you SO much!
