At a certain supplier, a machine of type A costs $20,000 and a machine of type B costs $65,000. Each machine can be purchased by making a 20 percent down payment and repaying the remainder of the cost and the finance charges over a period of time. If the finance charges are equal to 40 percent of the remainder of the cost, how much less would 2 machines of type A cost than 1 machine of type B under this arrangement?	Choose the correct option:	A) $10,000	B) $11,200	C) $12,000	D) $12,800	E) $33,000
Total Cost of 2 Machines of Type A   = 20% of (Cost of 2 machine A) + remainder + 40 % remainder   = 20% of 40000 + (40000 - 20% of 40000) + 40% of (40000 - 20% of 40000)   = 52800   Total Cost of 1 Machine of Type B   = 20% of (Cost of 1 machine B) + remainder + 40 % remainder   = 20% of 65000 + (65000 - 20% of 65000) + 40% of (65000 - 20% of 65000)   = 85800   Diff = 66000 - 85800 = 33000   Hence, $33,000.
