Question: Jaron wants to raise enough money selling candy bars to win the Nintendo Switch prize. He needs 2000 points for the Nintendo Switch. He has already sold 8 chocolate bunnies that are worth 100 points each. Each Snickers bar he sells earns 25 points. How many Snickers bars does he need to sell the win the Nintendo Switch?
Answer with step-by-step thinking: Jaron has earned a total of 8 * 100 points = 800 points. To win the Switch he needs to earn 2000 - 800 = 1200 points. Therefore, he needs to sell 1200 / 25 = 48 Snickers bars.
So the answer is 48.


Question: In a class of 30 students, the teacher polls the students on their favorite subject. 1/5 of the students like Math, and 1/3 like English. 1/7 of the remaining students like Science. The rest don’t have a favorite subject. How many students don’t have a favorite subject?
Answer with step-by-step thinking: 30 x 1 / 5 = 6 students like Math. 30 x 1 / 3 = 10 students like English. So, 6 + 10 = 16 students like either Math or English. Thus, 30 - 16 = 14 students neither like Math nor English. Since 1 / 7 of the remaining like Science, therefore 14 x 1 / 7 = 2 students like Science. Hence, 14 - 2 = 12 students neither likes the 3 subjects.
So the answer is 12.


Question: Nancy is filling an aquarium for her fish. She fills it halfway and goes to answer the door. While she's gone, her cat knocks the aquarium over and spills half the water in it. Then Nancy comes back and triples the amount of water in the aquarium. If the aquarium is 4 feet long, 6 feet wide, and 3 feet high, how many cubic feet of water are in the aquarium?
Answer with step-by-step thinking:

First calculate the volume of the aquarium by multiplying its length, width and height: 4 ft * 6 ft * 3 ft = 72 cubic ft. Then figure out what proportion of the aquarium is full after the cat knocks it over: 1 / 2 * 1 / 2 = 1 / 4. Then figure out what proportion of the aquarium is full after Nancy refills it: 3 * 1 / 4 = 3 / 4. Now multiply the proportion of the aquarium that's full by the aquarium's volume to find out how much water is in it: 72 cubic ft * 3 / 4 = 54 cubic ft.
So the answer is 54.
