[Question]The mayor commissioned two artists to paint 50 murals around the city. Once the work was completed, Celina was paid $1,000 more than 4 times the amount Diego got. If the mayor paid the two a total of $50,000, how much did Diego get?
[Answer]Let d be Diego’s payment. Both artists were paid (1000 + 4 * d ) + d = 50000 dollars. This means that 5d = (50000 - 1000) dollars. Therefore Diego was paid d = 49000 / 5 = 9800 dollars. The answer is 9800.

[Question]Phil has 10 books that are all 100 pages each. He moves to a new home and during the move, 2 books are lost. How many pages worth of books does Phil have left?
[Answer]Phil starts with 10 books and loses 2, for 10 - 2 = 8 books. Each of Phil's remaining books has 100 pages, so he has 8 * 100 = 800 pages worth of books. The answer is 800.

[Question]Kim loves to knit sweaters and can knit as many as 10 sweaters in a day if she gets the time. On a particular week, she knit 8 sweaters on Monday, 2 more sweaters on Tuesday than on Monday, 4 fewer sweaters on both Wednesday and Thursday than on Tuesday, and half the number of sweaters she had knit on Monday on Friday. Calculate the total number of sweaters she knit that week.
[Answer]If she knit 8 sweaters on Monday and 2 more on Tuesday, she knit 8 + 2 = 10 sweaters on Tuesday. The total number of sweaters she had knit on Monday and Tuesday is 10 + 8 = 18. On Wednesday, she knit four fewer sweaters than the number she knit on Tuesday, which totals 10 - 4 = 6 sweaters. By Wednesday, she had knit 18 + 6 = 24 sweaters. On Thursday, she knit the same number of sweaters she had knit on Thursday, giving a total of 24 + 6 = 30 sweaters. On Friday, she knit half the number of sweaters she had knit on Monday, which totals 1 / 2 * 8 = 4 sweaters on Friday. So far, she has knit 30 + 4 = 34 sweaters by Friday. The answer is 34.

[Question]Jack has a grove with 4 trees by 5 trees. It takes 6 minutes to clean each tree. He gets help to clean the trees so it only takes half as long. How many hours did he spend cleaning trees?

There were 4 * 5 = 20 trees to clean. So it took 20 * 6 = 120 minutes. That is 120 / 60 = 2 hours. So he spent 2 / 2 = 1 hour cleaning. The answer is 1.
