Question

一位店主以每支 $0.10 的价格买入 $1500$ 支铅笔。如果他以每支 $0.25 出售，那么他必须卖出多少支，才能恰好获利 $100.00？

A store owner bought $1500$ pencils at $0.10 each. If he sells them for $0.25 each, how many of them must he sell to make a profit of exactly $100.00?

$400$

$667$

$1000$

$1500$

$1900$

答案：C

知识点：钱币

难度评级：900

解答：

铅笔成本为 $1500 \times \$0.10 = \$150$ 。要获利一百美元，收入必须是 $\$150 + \$100 = \$250$ 。

每支售价二十五美分，所以必须卖出 $\dfrac{\$250}{\$0.25} = 1000$ 支。

所以正确答案是 C。

The pencils cost $1500 \times \$0.10 = \$150.$ To make a $100 profit, the revenue must be $\$150 + \$100 = \$250.$

At $0.25 each, he must sell $\dfrac{\$250}{\$0.25} = 1000$ pencils.

Thus, the correct answer is C .
