Answer:
A. Draw the cash flow diagram.
since the site doesn't include a drawing tool I just prepared a table to depict cash flows associated to years one through four:
Year Cash inflows
1 $50 million
2 $60 million
3 $70 million
4 $100 million
B. What is the present worth of the gains for the first three years?
- the present value of the first three cash flows = $50/1.1 + $60/1.1² + $70/1.1³ = $45.45 + $49.59 + $52.59 = $147.63 million
C. What is the present worth of the gains for all four years?
- the present value of the first three cash flows = $50/1.1 + $60/1.1² + $70/1.1³ + $100/1.1⁴ = $45.45 + $49.59 + $52.59 + $68.30 = $215.93 million
D. What is the equivalent uniform annual worth of the gains through year four?
- equivalent annual worth = (NPV x r) / [1 - (1 + r)⁻ⁿ] = ($215.93 x 0.1) / [1 - (1 + 0.1)⁻⁴] = 21.593 / 0.31699 = $68.12 million
