[Question]Each slice of cheesecake contains 350 calories. If there are a total of 2800 calories in every cheesecake, and Kiley ate 25% of the cheesecake, how many slices of cheesecake did Kiley eat?
[Answer]If there are 2800 calories in every cheesecake, and each slice of cheesecake contains 350 calories, then the cheesecake has 2800 / 350 = 8 slices. If Kiley ate 25% of the cheesecake, then she ate 8 * 0.25 = 2 slices of cake. The answer is 2.
Q: The lunchroom is full of students: 40% are girls and the remainder are boys. There are 2 monitors for every 15 students. There are 8 monitors. Every boy drinks, on average, 1 carton of milk, and every girl drinks, on average, 2 cartons of milk. How many total cartons of milk are consumed by the students in the lunchroom?
A: There is 1 monitor for every fifteen students because 30 / 2 = 15. There are 120 students because 8 x 15 = 120. 60% of the lunchroom is boys because 100 - 40 = 60. There are 72 boys because 120 x .6 = 72. There are 48 girls because 120 x .4 = 48. The boys drink 72 cartons of milk because 72 x 1 = 72. The girls drink 96 cartons of milk because 48 x 2 = 96. They drink 168 cartons of milk because 72 + 96 = 168. The answer is 168.
Question: Anthony keeps a bottle of vinegar in his cupboard for 2 years. Each year 20% of the vinegar evaporates. What percent of the vinegar is left after 2 years?
Answer: First find what percent of the vinegar is still in the bottle after each year: 100% - 20% = 80%. Then multiply the amount of vinegar left after one year by the percentage left after each year to find how much is left after 2 years: 80% * 80% = 64%. The answer is 64.
