Question

Booster Club 从一月到四月的糖果销售额如图所示。平均每月销售额是多少美元？

Candy sales of the Boosters Club for January through April are shown. What were the average sales per month in dollars?

$\ 60$

$\ 70$

$\ 75$

$\ 80$

$\ 85$

四个月的销售额分别为 $100,60,40$ 和 $120$ 美元。

它们的平均值为 $\dfrac{100+60+40+120}{4}$ $=\dfrac{320}{4}$ $=80$ 美元。

所以正确答案是 D。

The four monthly sales are $100,60,40,$ and $120$ dollars.

Their average is $\dfrac{100+60+40+120}{4}$ $=\dfrac{320}{4}$ $=80$ dollars.

Thus, D is the correct answer.
