Q: Lyle wants to buy himself and his friends a sandwich and a pack of juice. A sandwich costs $0.30 while a pack of juice costs $0.2. If Lyle has $2.50, how many of his friends can have a sandwich and a pack of juice?
A: A sandwich and a pack of juice cost $0.3 + $0.2 = $0.50. With Lyle's $2.50, he can buy $2.50 / $0.50 = 5 sets of sandwiches and juice. Therefore, 5 - 1 = 4 of his friends can have a sandwich and a pack of juice since the other 1 set is for Lyle himself. The answer is 4.
Question: In one day, 200 people visit The Metropolitan Museum of Art in New York City. Half of the visitors are residents of New York City. Of the NYC residents, 30% are college students. If the cost of a college student ticket is $4, how much money does the museum get from college students that are residents of NYC?
Answer: The number of visitors that are residents of NYC is 200 / 2 = 100 visitors. The number of NYC resident visitors that are college students is 100 * 0.30 = 30 visitors. The money from the college students that are residents of NYC is 30 * $4 = $120. The answer is 120.
[Question]A man drives 60 mph for 3 hours. How fast would he have to drive over the next 2 hours to get an average speed of 70 mph?
[Answer]To have an average speed of 70 mph over 5 hours he needs to travel 70 * 5 = 350 miles. He drove 60 * 3 = 180 miles in the first 3 hours. He needs to travel another 350 - 180 = 170 miles over the next 2 hours. His speed needs to be 170 / 2 = 85 mph. The answer is 85.
Q: Drew is 5 years older than Maya. Peter is 4 years older than Drew. John is 30 and is twice as old as Maya. In 2 years, Jacob will be exactly half of Peter’s age. How old is Jacob now?
A: If John is 30 and twice as old as Maya then Maya is 30 / 2 = 15 years old. Drew is 5 years older than Maya so Drew is 15 + 5 = 20 years old. Peter is 4 years older than Drew so is 20 + 4 = 24 years old. In 2 years, Peter will be 24 + 2 = 26 years old. Half of Peter’s age in 2 years will be 26 / 2 = 13 years old and Jacob’s age in 2 years. Jacob now is 13 - 2 = 11 years old. The answer is 11.
Question: Mark and Peter dug ponds in their backyards. Mark’s pond is 4 feet deeper than 3 times Peter’s pond. If Mark’s pond is 19 feet deep, what is the depth of Peter’s pond?
Answer: Let’s use p for the number of feet in Mark’s pond. 3 * p + 4 = 19. 3 * p = 19 - 4 = 15. 3p = 15. p = 5. The answer is 5.
Q: Dolly wants to ride the Ferris wheel twice, the roller coaster three times, and the log ride seven times. The Ferris wheel costs 2 tickets, the roller coaster costs 5 tickets and the log ride costs 1 ticket. Dolly has 20 tickets. How many more tickets should Dolly buy?
A:
It costs 2 rides x 2 tickets / ride = 4 tickets to ride the Ferris wheel twice. It costs 3 rides x 5 tickets / ride = 15 tickets to ride the roller coaster three times. It costs 7 rides x 1 ticket / ride = 7 tickets to ride the roller coaster seven times. In total Dolly needs 4 tickets + 15 tickets + 7 tickets = 26 tickets. Dolly needs to buy 26 tickets - 20 tickets = 6 more tickets. The answer is 6.
