Q: In one of the teacher's meetings, it was agreed that each class will contribute $90 for a school activity. The class of Miss Evans has $14 class funds and they decided to use it to lessen the contribution of each student. If the remaining amount will be divided among 19 students, how much will each student contribute?
A: The 19 students will divide equally the remaining $90 - $14 = $76. So, each student will contribute $76 / 19 students = $4 / student. The answer is 4.
Question: Terry drives at a speed of 40 miles per hour. He drives daily forth and back from his home to his workplace which is 60 miles away from his home. How many hours does Terry spend driving from home to the workplace and then back?

[Question]Milly is figuring out how long she needs to spend studying. She knows that her math homework will take 60 minutes. Her geography homework will take half as long as her math homework, and her science homework will take time equal to the mean amount of time she spent studying math and geography. How many minutes does Milly spend studying?
[Answer]First find how long Milly spends studying geography by dividing her math homework time by 2: 60 minutes / 2 = 30 minutes. Now find the total amount of time Milly spent on math and geography: 30 minutes + 60 minutes = 90 minutes. Now calculate the mean amount of time Milly spends on math and geography by dividing the total time spent by the number of subjects, which is 2: 90 minutes / 2 = 45 minutes. Now add the time Milly spent on all three subjects to find the total: 45 minutes + 30 minutes + 60 minutes = 135 minutes. The answer is 135.
Q: Elroy decides to enter a walk-a-thon and wants to make sure he ties last year's winner's cash collection. Last year, walkers earned $4 a mile. This year walkers earn $2.75 a mile. If last year's winner collected $44, how many more miles will Elroy walk than last year's winner to collect the same amount of money?
A: Last year's winner walked 11 miles because 44 / 4 = 11. Elroy has to walk 16 miles to collect $44 because 44 / 2.75 = 16. Elroy will walk 5 more miles because 16 - 11 = 5. The answer is 5.
Question: Jordan noticed that there are 2 cars in his driveway that each have 4 wheels. There are 2 bikes and a trash can that each have 2 wheels. There is also a tricycle and a pair of old roller skates. How many wheels are there?
Answer: There are 2 cars with 4 wheels each so that's 2 * 4 = 8 wheels. Two bikes and a trash can each have 2 wheels so that's 3 * 2 = 6 wheels. Each roller skate has 4 wheels and there is a pair, which means 2 skates for a total of 4 * 2 = 8 wheels. Including the 3 wheels on the tricycle, there are 8 from the car, 6 from bikes and a trashcan and 8 from roller skates for a total of 3 + 8 + 6 + 8 = 25 wheels. The answer is 25.
Q: The math teacher would be happy if the class average test score was at least 85. There are 10 students in the class, 5 of which scored a 92 on the test and 4 of which scored an 80. What would the last student have to score to at least make the teacher happy?
A:
5 students scored a combined total of 92 * 5 = 460. 4 additional students scored a combined total of 80 * 4 = 320. 9 students therefore scored a combined total of 460 + 320 = 780. We know the total combined score for 10 students must be at least 85 average * 10 students = 850. Therefore, the last student must score at least an 850 - 780 = 70. The answer is 70.
