Question: Saturday at the ice cream shop, there were twice as many people who ordered vanilla ice cream as ordered chocolate ice cream. If 220 people ordered ice cream on Saturday, and 20% of those ordered vanilla ice cream, how many people ordered chocolate ice cream? Think carefully first, then make a decision:
If 20% of 220 customers ordered vanilla, then there were 0.2 * 220 = 44 customers who ordered vanilla. If there were twice as many people who ordered vanilla as chocolate, then 44 / 2 = 22 customers ordered chocolate. So the answer is 22.
