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 + 25 m +  45 = 50 + 60 m is the required equation.

Step-by-step explanation:

First Runner :  Savings = $112

                         Gift = $45

                       Saving per month = $25

Second Runner :  Savings = $50

                         Saving per month = $60

m: number of months it takes to save equal amount.

Now, total money saved by First runner = 112  + 45 + m x 25

and total money saved by second runner = 50 + m x 60

And  both of them saves equal amount in m days.

⇒  112  + 45 +  25 x m =  50 + m x 60

or, 112 + 25 m +  45 = 50 + 60 m is the required equation.
