解释:这是固定搭配,用名词room修饰名词number.变复数时(前有both),则room不用变,只需把number变成复数numbers.

A中的number为单数,不符合句意;

C中的room's不妥,就算用所有格也必须是rooms' numbers;

D中的room前面应该用定冠词the,且room也必须变成复数形式.

解释:cost的主语必须是sth/it,一般构成it cost sb + 金钱 + to do sth句型,排除A;

B/C中的spned/buy是及物动词,后面不能没有宾语sth,其对应短语分别是:sb spend + 钱 + on sth / (in) doing sth 和 sb buy sth for + 钱,排除.

而pay可以做不及物动词,意思也是“付钱/付款”,正解.
