问题 Room prices are regularly $100, but for each additional room rented by a group, the price is reduced by $3 for each room. For example, 1 room costs $100, 2 rooms cost 2 x $97 = $ 194, 3 rooms cost 3 x $94 = $282, and so on. What is the total cost of renting 6 rooms?
选项
答案 510
解析 由题干中的例子类推可知租六间房子的房租为6×[100一3×(6—1)]=510。
