Question: An aquarium holds an equal number of clownfish and blowfish. 26 of the blowfish stay in their own tank, and the remaining blowfish swim into a display tank. An equal number of clownfish join the blowfish in the display tank, but then a third of these clownfish swim back into their own tank. If the aquarium holds a combined total of 100 fish, how many clownfish are now in the display tank?
Answer: There is an equal number of clownfish and blowfish, which means there are 100 fish / 2 = 50 blowfish. Since some stay in their tanks, there are 50 blowfish – 26 blowfish = 24 blowfish in the display tank. There were the same amount of clownfish until 24 clownfish / 3 = 8 clownfish swam back to their own tank. This leaves 24 clownfish – 8 clownfish = 16 clownfish in the display tank. The answer is 16.
[Question]Miss Grayson's class raised $50 for their field trip. Aside from that, each of her students contributed $5 each. There are 20 students in her class, and the cost of the trip is $7 for each student. After all the field trip costs were paid, how much is left in Miss Grayson's class fund?
[Answer]The contribution of the students amounted to $5 x 20 = $100. So Miss Grayson's class had $100 + $50 = $150 in all. The cost of the field trip amounted to $7 x 20 = $140. Therefore, the class of Miss Grayson is left with $150 - $140 = $10. The answer is 10.
[Question]Mary is building a mosaic for her school cafeteria's wall. It will be 10 feet tall and 15 feet long. Each tile she uses is 1 inch square. How many tiles will she need?
[Answer]
First convert the length of the mural to inches: 15 feet * 12 inches / foot = 180 inches. Then convert the height of the mural to inches: 10 feet * 12 inches / foot = 120 inches. Then multiply the length and the height to find the total area of the mural: 180 inches * 120 inches = 21600 square inches. Since each tile is 1 square inch, this is also the number of tiles she needs. The answer is 21600.
