商店从厂家购进电视机每台$87．89，通常每台电视机的售出价是购进价的225％，但使用优惠券可以优惠25%，请问使用优惠券的顾客买一台电视需要花多少钱？
A store buys televisions from a factory for $ 87.89 each. The store normally sells one of these televisions for 225 percent of the factory cost, but a store coupon （优惠券） gives 25 percent off this selling price. Without tax, how much does a customer （顾客） with this coupon pay for the television？
