'Please help I'm so confused:

Scribbles Inc. operates a chain of coffee shops. The company is considering two possible expansion plans. Plan A would open eight smaller shops at a cost of $8,440,000. Expected annual net cash inflows are $1,400,000 with zero residual value at the end of ten years. Under Plan B, Scribbles would open three larger shops at a cost of S8,340,000. This plan is expected to generate net cash inflows of $1,200,000 per year for ten years, the estimated life of the properties. Estimated residual value is $1,075,000. Scribbles uses straight-line depreciation and requires an annual return of 8%. (Click the icon to view the present value annuity factor table.)(Click the icon to view the present value factor table.)
