Required:

1a. Compute the cash payback period for each project.

	Cash Payback Period
Plant Expansion	2 years
Retail Store Expansion	2 years

1b. Compute the net present value. Use the present value of $1 table above. If required, round to the nearest dollar.

	Plant Expansion	Retail Store Expansion
Total present value of net cash flow	$	$
Less amount to be invested
Net present value	$	$

2. Because of the timing of the receipt of the net cash flows, the plant expansion offers a higher net present value .
