Q: Luis is driving 80 miles in 2 hours. How far will he go in 15 minutes?
A: Luis drives 80 / 2 = 40 miles in 1 hour. Since there are 60 minutes in 1 hour, then he drives 40 / 60 = 2 / 3 of a mile in 1 minute. So in 15 minutes, he will go 2 / 3 x 15 = 10 miles far. The answer is 10.
Question: 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?
Answer: 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.

Q: Haily wants to go to the salon and do her nails, cut her hair and do a facial cleaning. She doesn't want to spend much, so she called 3 salons to get their prices: Gustran Salon, Barbara's Shop, and The Fancy Salon. At Gustran Salon, the haircut is $45, the facial cleaning is $22 and the nails are $30. At Barbara's shop, the nails are $40, the haircut is $30 and the facial cleaning is $28. And, at the Fancy Salon, the facial cleaning is $30, the haircut is $34 and the nails are $20. How much would Haily spend at the cheapest salon?
A: So first, we should add the prices of all salons. At Gustran Salon, the total price is: $45 + $22 + $30 = $97. The total price at Barbara's shop is: $40 + $30 + $28 = $98. The total price at The Fancy Salon is: $30 + $34 + $20 = $84. At Gustran salon she would spend $97, at Barbara's Shop she would spend $98, and at The Fancy Salon she would spend $84, so she would spend $84 at the cheapest salon. The answer is 84.

Answer: The loaves of bread cost 5 * $5 = $25. The orange juice cost 4 * $2 = $8. Wyatt’s total cost is $25 + $8 = $33. Wyatt is left with the initial $74 - $33 = $41. The answer is 41.
Q: Every morning, Carla puts 79 apples in her backpack to eat for lunch. Unfortunately, Buffy stole some of Carla's apples on the school bus, and 26 apples fell out of a hole on the bottom. So at lunchtime, Carla only had 8 apples remaining. How many apples did Buffy steal from Carla?
A:
Let B be the number of apples that Buffy stole. Then 79 - B - 26 = 8. Combining constants produces 53 - B = 8. Adding B to both sides produces 52 = B + 8. Thus the number of apples stolen by Buffy is B = 53 - 8 = 45. The answer is 45.
