Question: John works a job that offers performance bonuses. He makes $80 a day and works for 8 hours. He has the option of working hard to earn the performance bonus of an extra $20 a day, but the extra effort results in a 2-hour longer workday. How much does John make per hour if he decides to earn the bonus?
Answer: First, we need to determine the length of John's workday if he decides to earn the bonus. We do this by performing 8 + 2 = 10 hours for his workday. Next, we need to determine his overall pay. We do this by performing 80 + 20 = 100 dollars a day. We then determine John's hourly rate by dividing his pay by the number of hours worked, performing 100 / 10 = 10 dollars an hour. The answer is 10.
[Question]A Statistics student wants to find out the average daily allowance of the middle school students. According to his survey, 2/3 of the students receive an average of $6 allowance per day while the rest gets an average of $4 a day. If he surveyed 60 students, what is the total amount of money those 60 students get in a day?
[Answer]There are 60 students x 2 / 3 = 40 students who have a $6 daily allowance. While there are 60 students - 40 students = 20 students who have a $4 daily allowance. The sum of the allowances of the 40 students who received $6 daily is 40 students x $6 / day = $240. The sum of the allowances of the 20 students who received $4 daily is 20 students x $4 / day = $80. The total daily amount of money of those 60 students is $240 + $80 = $320. The answer is 320.

Question: Alice and Bob decided to bake cookies for their first date. Alice baked 74 chocolate chip cookies and Bob baked 7 peanut butter cookies. After accidentally throwing some on the floor, Alice baked 5 more cookies and Bob baked 36 more. If they had 93 edible cookies at the end, how many were accidentally thrown on the floor?
Answer: Before throwing the cookies, Alice and Bob baked 74 + 7 = 81 cookies. After throwing the cookies, they baked 5 + 36 = 41 cookies. In total, they baked 81 + 41 = 122 cookies. They threw 122 - 93 = 29 cookies on the floor. The answer is 29.
