An industrial firm can purchase a special machine for $22,000. A down payment of $2,500 is required, and the balance can be paid in 5 equal year-end-installments at 14% interest on the unpaid balance. As an alternative the machine can be purchased for $19,000 in cash. If the firm's MARR is 20%, determine which alternative should be accepted. Use the present worth on incremental investment approach.
