Question: There are 110 calories in a serving of cheese. Rick buys the large blocks that have 16 servings per block. If Rick has already eaten 5 servings of cheese, how many calories are remaining in the block?
Answer with step-by-step thinking: The block has 16 servings and he has eaten 5 servings leaving 16 - 5 = 11 servings of cheese. There are 11 servings of cheese left and each serving is 110 calories for a total of 11 * 110 = 1,210 calories.
So the answer is 1210.


Question: Randy has $30. He spent $10 buying his lunch. He spent a quarter of the money he had left on an ice cream cone. What is the amount of money, in dollars, Randy has left?
Answer with step-by-step thinking: Randy has 30 - 10 = 20 dollars left after buying lunch. Randy spent 20 / 4 = 5 dollars on the ice cream cone. Randy has 20 - 5 = 15 dollars left.
So the answer is 15.


Question: Lucille is painting her room. Two of her walls are 3 meters wide and 2 meters tall. The third wall is 5 meters wide and 2 meters tall. The final wall is 4 meters wide and 2 meters tall. If each can of paint covers 2 square meters, how many cans of paint does Lucille need?
Answer with step-by-step thinking:
For the first set of walls, each wall covers 3 meters wide * 2 meters tall = 6 square meters. There are two of these walls, so this becomes a total of 6 meters * 2 walls = 12 square meters. The third wall covers 5 meters wide * 2 meters tall = 10 square meters. The final wall covers 4 meters wide * 2 meters tall = 8 square meters. So in total, the paint needs to cover 12 + 10 + 8 = 30 metres. Since each can covers 2 meters, Lucille needs 30 meters / 2 = 15 cans of paint.
So the answer is 15.
