At a certain supplier, a machine of type A costs $20,000 and a machine of type B cost $50,000.Each machine can be purchased by making a 20 percent down payment and repaying the remainder of the cost and the finance changes over a period of time.If the finance changes 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?
