Christina has 3 snakes. 1 snake is 2 feet long. Another snake is 16 inches long. The last snake is 10 inches long. How many inches are all of her snakes combined?
Let's think: The first snake is 24 inches because there are 12 inches in a foot. The snakes are 24 + 16 + 10 = 50 inches long.. The answer is: 50.

Sarah interviewed 450 students at her school and asked them which fruit they liked best - oranges, apples, pears or strawberries. 70 students said they liked oranges, 120 students said they liked pears, and 147 students said they liked apples. How many students picked strawberries as their favorite fruit from the list?
Let's think: First, you have to add the number of students that liked the three other fruits. Therefore, you have to add 70 + 120 + 147. This gives you a sum of 337. We know that 450 students were interviewed, so you have to subtract 337 from 450 to get the number of students who liked strawberries. 450 - 337 = 113 students liked strawberries best out of all of the fruits.. The answer is: 113.

Michael scored 260 points during his junior year on the school basketball team. He scored 20% more points during his senior year. How many points did he score during both years?
Let's think: In his senior year, Michael scored 260 × 1.20 = 312 points. In both his senior and junior years Michael scored 260 + 312 = 572 points.. The answer is: 572.

The number of pencils that Colleen has more than Joy is 50 - 30 = 20 pencils. If each pencil was sold at $4 each, Colleen paid $4 * 20 = $80 more for the 20 extra pencils she has more than Joy.. The answer is: 80.
