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? a.112 – 25m + 45 = 50 – 60mb.112 + 25 + 45m = 50m + 60c.112 + 25 – 45m = –50m + 60d.112 + 25m + 45 = 50 + 60m
