(1) Warehouse W sold 10 percent more sofas this year than it did last year.

(2) Warehouse W's selling price per sofa was $30 greater this year than it was last year.

ANS:E

想請問what percent greater this year than last year

的數學式是: 今年Sale-去年sale/今年sale 嗎???

還是除以去年sale??

請問 多百分之幾的分母是甚麼?? 今年營收還是去年營收???

問今年比去年多百分之幾，所以今年要放在分子，去年放在分母
因無法求出一個百分比數字，所以答案為 E
