Apopka Urgent Care, a for-profit medical practice, has decided to acquire a new top-of-the-line magnetic resonance imaging (MRI) scanner. One alternative would be to purchase the equipment outright for $90,000. If purchased, the practice could borrow the amount needed from a local bank at a 6 percent interest rate. Also, if purchased, the practice would have to sign a maintenance contract with a vendor that would cost $3,000 annually, payable at the beginning of each year. Alternatively, the practice could lease the machine on a four-year guideline lease with a payment of $28,000 payable at the beginning of each year. The lease includes maintenance. The MRI scanner falls into the MACRS three-year class (allowances are 33, 45, 15, and 7 percent in Years 1 through 4, respectively), the machine's estimated residual value is $12,000, and the practice's federal-plus-state tax rate is 35 percent. Should the practice buy, or should the practice lease the equipment? Please explain. its payable at the begining of the year
