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?
Let's think: 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.. The answer is: 22.

John buys a gaming PC for $1200. He decides to replace the video card in it. He sells the old card for $300 and buys a new one for $500. How much money did he spend on his computer, counting the savings from selling the old card?
Let's think: He spent an extra 500 - 300 = $200 on the video card. That means the total cost was 1200 + 200 = $1400.. The answer is: 1400.

Stefan, Vail, and Aiguo collected seashells. Stefan had 16 more seashells than Vail. Vail had 5 less than Aiguo. Aiguo had 20 seashells. How many seashells did the 3 children have in total?
