Question

Susan 有 $\$50$ 可以在嘉年华会上花。她花了 $\$12$ 买食物，又花了这个数的两倍去玩游乐项目。她还剩多少美元可以花？

Susan had $\$50$ to spend at the carnival. She spent $\$12$ on food and twice as much on rides. How many dollars did she have left to spend?

$12$

$14$

$26$

$38$

$50$

知识点：钱币

Susan 在游乐项目上花了 $2\cdot 12=24$ 美元，所以她一共花了 $12+24=36$ 美元。

她还剩 $50-36=14$ 美元。

所以正确答案是 B。

Susan spent $2\cdot 12=24$ dollars on rides, so she spent $12+24=36$ dollars total.

She had $50-36=14$ dollars left.

Thus, B is the correct answer.
