Answer this question:The teacher agrees to order pizza for the class. For every student in the class, she will buy 2 pieces of cheese and 1 piece of onion and they will eat exactly that amount. A large pizza has 18 slices. She orders 6 total pizzas and there are 8 pieces of cheese and 4 pieces of onion leftover. How many students are in the class?
Cheese pizzas are 2 / 3 of the pizza's purchased because 2 / (2 + 1) = 2 / 3. She buys 4 cheese pizzas because 6 x (2 / 3) = 4. These give her 72 pieces of cheese pizza because 4 x 18 = 72. The students at 64 pieces of cheese because 72 - 8 = 64. There are 32 students in her class because 64 / 2 = 32.
The answer is 32.

Answer this 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?
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.

Answer this question:John drinks 2 energy drinks. 1 of them is a 12-ounce drink with 250 grams of caffeine. The second drink is 3 times more caffeinated per ounce but only 2 ounces. He then takes a caffeine pill that has as much caffeine as his 2 drinks combined. How much caffeine did he consume?
The second drink was 2 / 12 = 1 / 6 the size of the first drink. So it had 1 / 6 * 3 = 1 / 2 the caffeine. That means it had 1 / 2 * 250 = 125 grams of caffeine. So the total amount of caffeine he drank was 125 + 250 = 375 grams. So he consumed 375 * 2 = 750 grams of caffeine for the day.
The answer is 750.
