Need some help on this problem, not sure how to do it at all!

We are evaluating a project that costs $1,582,000, has a seven-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 87,100 units per year. Price per unit is $34.30, variable cost per unit is $20.55, and fixed costs are $751,000 per year. The tax rate is 30 percent, and we require a return of 12 percent on this project. Suppose the projections given for price, quantity, variable costs, and fixed costs are all accurate to within
