[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?
[Answer]: 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.
So the answer is 750.

[Question]: The size of a bathroom is 96 sq ft. If the width of the bathroom is 8 feet and the owner wants to extend it by 2 feet on each side, what is the new area of the bathroom?
[Answer]: The original length of the bathroom is 96 sq ft / 8 ft = 12 ft. The new length of the bathroom is 12ft + 2 ft = 14 ft. The new width of the bathroom is 8 ft + 2 ft = 10 ft. The new area of the bathroom is 14ft x 10 ft = 140 sq ft.
So the answer is 140.

[Question]: Michelle is bringing sandwiches to work to give to her co-workers. She gives 4 sandwiches to one of her co-workers and keeps twice this amount for herself. If she had originally made 20 sandwiches, how many sandwiches does she have left to give to her other co-workers?
[Answer]:
Michelle kept 4 sandwiches * 2 = 8 sandwiches for herself. This leaves 20 total sandwiches – 4 sandwiches for a coworker – 8 sandwiches for herself = 8 sandwiches for her other co - workers.
So the answer is 8.
