I am confused on how to find the ATCF's

A construction company is considering whether to lease or buy equipment for its new 4-year project. If they buy the equipment, it will have an initial investment cost of $640,000 with annual costs of $44,000. At the end of the 4 years the equipment can be sold for an estimated $384,000. For tax purposes, the company will use MACRS-ADS depreciation on the equipment. If they decide to lease, it will cost them $210,000 per year all inclusive. However, they will also be required to make a $125,000 initial deposit that will be refunded in full at the end of the 4-year lease. The refund is not taxable. The company's marginal effective tax rate is 25% and the capital gain tax rate is 15%. The after-tax MARR is 18% per year. Based on the after-tax cash flows, what would you recommend, leasing or purchase? Click the icon to view the partial listing of depreciable assets used in business Click the icon to view the interest and annuity table for discrete compounding when the MARR is 18% per year. Use the table to determine the ADS recovery period for construction equipment, and hence the depreciations, taxes and after-tax cash flows for each of the four years for the lease and purchase options. (Costs should be negative cash flows and revenues positive. Round to the nearest dollar.) Year ATCF (Lease) ATCF(Purchase) DD0000 ODDDDD Calculate the PW values for the two options. PW(Lease) (18%) = $ (Round to the nearest dollar.) PW(Purchase)(18%) = $ (Round to the nearest dollar.) Based on the PW values, which option is more economical? O A. Purchase O B.
