Question and rationale: The question is: Mary, Jess, and Christina want to decorate a party room with balloons. Each person inflates balloons at different speeds, and they only have 30 minutes to inflate as many balloons as possible. Mary inflates 10 balloons per minute, Jess inflates 7 balloons per minute and Christina came 15 minutes late and was the slowest one inflating 4 balloons per minute. How many balloons can they inflate before running out of time?
Step-by-step reasoning process: Mary will inflate a total of 10 balloons / minute x 30 minutes = 300 balloons. Jess will inflate a total of 7 balloons / minute x 30 minutes = 210 balloons. Christina will inflate a total of 4 balloons / minute x 15 minutes = 60 balloons. Combining all balloons, they made 300 balloons + 210 balloons + 60 balloons = 570 balloons.

Question and rationale: The question is: The chances of making the junior high basketball team start at 10% if you're 66 inches and increase 10% for every additional inch of height. Devin starts out as 65 inches tall, then grows 3 inches. What are his chances of making the basketball team?
Step-by-step reasoning process: First find Devin's new height by adding his growth to the original height: 65 inches + 3 inches = 68 inches. Then subtract 66 inches from Devin's height to find how many extra inches of height he has: 68 inches - 66 inches = 2 inches. Then multiply the number of extra inches by the percentage increase per inch to find the total percentage increase in his chances: 2 inches * 10% / inch = 20%. Then add the percentage increase to the base percentage to find Devin's overall chance of making the basketball team: 10% + 20% = 30%.

Question and rationale:
The question is: A cobbler can mend 3 pairs of shoes in an hour. From Monday to Thursday, the cobbler works for 8 hours each day, and on Friday, he only works from 8am to 11am. How many pairs of shoes can the cobbler mend in a week?
Step-by-step reasoning process: From Monday to Thursday, the cobbler can mend 3 x 8 = 24 pairs of shoes a day. From Monday to Thursday, he can mend 24 x 4 = 96 pairs of shoes. On Friday, he works for 11 - 8 = 3 hours. On Friday, he can mend 3 x 3 = 9 pairs of shoes. In a week, he can mend 96 + 9 = 105 pairs of shoes.
