Problem: A man ate a total of 125 grapes in five days. Each day he ate 6 more grapes than he ate the previous day. How many grapes did he eat the first day?

Kate's response:
What I need to do to solve this problem: I need to find out how many grapes he ate the first day.

How I solved this problem:

25 25 25 25 +25 125

I divided 5 into 125. (Work shown.) It equalled 25. I found out that 25 is the middle number. 25 - 6 = 19 - 6 = 13. I subtracted 6 for 25, then I subtraced 6 more. Then I added 6 to 13 and added6 more to every answer. I went to 37. Then I added 13 to 19, then 19 to 32 . . . It equaled 125.

Answer: 13 grapes

How I checked this problem: This is how I checked my answer.

37- 6 = 31 -6 + 25 - 6 = 19 - 6 = 13.
