Q: There were 90 people at the summer picnic. There were 50 soda cans, 50 plastic bottles of sparkling water, and 50 glass bottles of juice. One-half of the guests drank soda, one-third of the guests drank sparkling water, and four-fifths of the juices were consumed. How many recyclable cans and bottles were collected?
A: The soda cans were consumed by 90 / 2 = 45 guests. The sparkling water was consumed by 90 / 3 = 30 guests. The juice bottles were consumed by 4 / 5 x 50 = 40 guests. In total there are 45 + 30 + 40 = 115 recyclable cans and bottles. The answer is 115.
Question: John pays for a candy bar with 4 quarters, 3 dimes, and a nickel. He got 4 cents back in change. How many cents did the candy bar cost?
Answer: The quarters came to 4 * 25 = 100 cents. The dimes were worth 3 * 10 = 30 cents. The nickel was 5 * 1 = 5 cents. So he paid 100 + 30 + 5 = 135 cents. Since he got 4 cents as change it cost 135 - 4 = 131 cents. The answer is 131.
[Question]Erin works in the school cafeteria serving soup. Each bowl of soup has 10 ounces, and Erin can serve 5 bowls per minute. If the pot of soup has 6 gallons of soup, how long will it take Erin to serve all the soup, rounded to the nearest minute? (There are 128 ounces to a gallon.)
[Answer]First find the number of ounces Erin serves per minute: 10 ounces / bowl * 5 bowls / minute = 50 ounces / minute. Then find the number of ounces in the pot: 6 gallons * 128 ounces / gallon = 768 ounces. Then divide the total amount of soup by the amount of soup Erin serves per minute: 768 minutes / 50 ounces / minute = 15.36 minutes, which rounds down to 15 minutes. The answer is 15.
Q: Austin bought his seven friends each a robot. Each robot costs $8.75. He was charged $7.22 total for tax. He left with $11.53 in change. How much did Austin start with?
A: First we need to find the total amount for the robots. 7 robots * $8.75 per robot = $61.25 in total. Now we need to add in the tax $61.25 for the robots + $7.22 for tax = $68.47 total spent in store. Now to find what was the beginning amount we take the $68.47 total spent in - store + $11.53 in change = $80 to start. The answer is 80.
Question: Brenda weighs 10 pounds more than 3 times Mel's weight. If Brenda weighs 220 pounds, what is Mel's weight?
Answer: Let Mel's weight be m. Brenda’s weight is 3 * m + 10 = 220 pounds. Thus 3m = 220 - 10 = 210 pounds. Therefore Mel's weight is m = 210 / 3 = 70 pounds. The answer is 70.
Q: A type C school bus contains 13 rows of seats, with an aisle running down the middle of the bus, splitting each row into two sections. If the school only allowed two students to sit in each section, how many students could be seated on the bus?
