Question: Jake can wash his car with 1 bottle of car wash soap 4 times. If each bottle costs $4.00, and he washes his car once a week for 20 weeks, how much does he spend on car soap?
Answer: 1 bottle of soap will last for 4 washes and he needs enough bottles for 20 weeks so 20 / 4 = 5 bottles. Each bottle cost $4.00 and he needs 5 bottles so he will spend $4 * 5 = $20.00 on car soap. The answer is 20.
[Question]Cecil has $600. Catherine has $250 less than twice as much as Cecil while Carmela has $50 more than twice Cecil's money. How much money do they have altogether?
[Answer]Twice as much as Cecil's money is $600 x 2 = $1200. So, Catherine has $1200 - $250 = $950. While Carmela has $1200 + $50 = $1250. Hence, they have a total of $600 + $950 + $1250 = $2800. The answer is 2800.
Q: Kelly needs school supplies to teach her class for an art project. She has 8 students and they will need 3 pieces of construction paper each. In addition to the construction paper, she needs to buy 6 bottles of glue for everyone to share. After Kelly purchases these supplies, she dropped half of them down a storm drain. Class is about to start, but she manages to rush to the store and buy 5 more pieces of construction paper. How many supplies are left?
A: Kelly needs 8 * 3 = 24 pieces of construction paper. She buys glue which grows the supplies to 24 + 6 = 30. Unfortunately, she dropped 30 / 2 = 15 supplies. Rushing to the store, she buys more construction paper bringing her supplies back to 15 + 5 = 20. The answer is 20.
Question: Rodney and Todd are rowing down a river that is 50 yards wide at one end. If the river's width increases from this end uniformly by 2 yards every 10 meters along, and they row along the river at a rate of 5 m/s, how long (in seconds) will it take them to get to the point where the river is 80 yards wide?
Answer: The difference in width between where they're starting from and their destination is 80 - 50 = 30 yards. The width increases 2 yards every 10 m along the river so they would have to cover (30 / 2) * 10 = 150 meters. Traveling at the rate of 5m / s, he will spend 150 / 5 = 30 seconds. The answer is 30.
[Question]Jean has three times as much money as Jane. They have a combined total of $76. How much money does Jean have?
[Answer]Let's assume the total amount of money that Jane has is m. Since Jean has 3 times as much money as Jane, he has 3 * m = 3m. Combined, Jean and Jane have a total of m + 3m = $76. This evaluates to 4m = $76. The total amount of money that Jane has, represented by m, is m = $76 / 4. Jane has m = $19. Since Jean has three times as much money as Jane, Jean has 3 * $19 = $57. The answer is 57.
[Question]Mikaela was repainting her bathroom. She bought 16 containers of paint to cover the four equally-sized walls. At the last minute, she decided to put tile on one wall in the bathroom and paint flowers on the ceiling with one container of paint instead. How many containers of paint will she have left over?
[Answer]
Mikaela would use 16 / 4 = 4 containers of paint per wall. To paint 3 walls, she will use 3 * 4 = 12 containers. After using 1 container for the ceiling, she will have 16 - 12 - 1 = 3 containers of paint left over. The answer is 3.
