单选题 The chart above shows how Jeff spent his earnings for one year. How much did Jeff spend for clothing?
(1)He spent $18 during the year on tennis balls.
(2)He spent $190 during the year on recreation

【正确答案】 B
【答案解析】[解析] 从图中可以看出,Jeff在衣服上的开支占他这一年总收入的26%,因此只要能求出总收入是多少,就可以求出他在衣服上所花钱的多少。(1)明显不充分,因为它与图中的数据联系不起来,从而也无法求出Jeff在衣服上所花的钱是多少;(2)充分,因为根据娱乐的开支是190美元,以及它占总开支的20%,很容易求出他的总支出是190÷20%美元,所以他在衣服上的支出是190÷20%×26%=247美元。
