Susan 在嘉年华上有 $50$ 美元可以花。她花了 $12$ 买食物，在游乐设施上花了这两倍的钱。她还剩下多少美元可以花？

(A) 12 12

(B) 14 14

(D) 38 38

(E) 50 50

Answer

Correct choice: (B)

正确答案：（B）

Solution

If Susan spent 12 dollars, then twice that much on rides, then she spent $12+12 \times 2=36$ dollars in total. We subtract $36$ from $50$ to get $\boxed{\textbf{(B)}\ 14}$

Susan 花了 12 美元，那么在游乐设施上花了两倍，即 $12+12 \times 2=36$ 美元总共。从 $50$ 中减去 $36$ 得到 $\boxed{\textbf{(B)}\ 14}$
