Two runners are saving money to attend a marathon. The first runner has $112 in savings, received a $45 gift from a friend, and will save $25 each month. The second runner has $50 in savings and will save $60 each month.

Which equation can be used to find m, the number of months it will take for both accounts to have the same amount of money?

112 – 25m + 45 = 50 – 60m
112 + 25 + 45m = 50m + 60
112 + 25 – 45m = –50m + 60
112 + 25m + 45 = 50 + 60m

112+45+25=50+60m, I would think.

Oh okay, well I'll still go through the answers, so that when you come back on you can check which one was right and why it was right.

Okay, the answer is D, because the guys/or girls are adding up all of their money (separately, in their own accounts, not all together), and there's no subtracting, and no negative numbers, because they didn't spend anything. But, there are months they need to multiply with certain amounts, because they earn that money by the month. 25 and 60 are their monthly earnings, but you don't know how many months they'll be earning the money. So m goes after both of those numbers.
