Q: Kyle has a newspaper-delivery route. Every Monday through Saturday, he delivers the daily paper for the 100 houses on his route. On Sunday, 10 of his customers do not get the Sunday paper, but he delivers 30 papers to other houses that get the newspaper only on Sunday. How many papers does Kyle deliver each week?
A: He delivers 6 * 100 = 600 papers. On Sunday, he delivers an additional 100 - 10 + 30 = 120 papers. He delivers a total of 600 + 120 = 720 papers each week. The answer is 720.

Q: There were 2450 sheets of paper that were evenly split into 5 binders. Justine took a binder and colored on one-half of the sheets of paper. How many sheets of paper did Justine use?
A: 2450 / 5 = 490 sheets of paper. 490 / 2 = 245 sheets of paper. Justine colored on 245 pieces of paper. The answer is 245.

Q: Martin rings the small bell 4 times more than 1/3 as often as the big bell. If he rings both of them a combined total of 52 times, how many times does he ring the big bell?
A:
Let s be the number of times the small bell rings, and b be the number of times the big bell rings. We know that s + b = 52 and s = 4 + 1 / 3b. Substituting the second equation into the first equation, we get 4 + 1 / 3b + b = 52. Subtracting 4 from both sides, we get 1 / 3b + b = 48. Combining like terms, we get 4 / 3b = 48. Dividing both sides of the equation by 4 / 3, we get b = 36. The answer is 36.
