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

Answer

Explanation:

Step1: Calculate first - runner's money

The first runner starts with $112, gets a $45 gift, and saves $25 per month. So the amount of money $A_1$ after $m$ months is $112 + 45+25m$.

Step2: Calculate second - runner's money

The second runner starts with $50 and saves $60 per month. So the amount of money $A_2$ after $m$ months is $50 + 60m$.

Step3: Set up the equation

We want to find when $A_1 = A_2$. So the equation is $112+25m + 45=50 + 60m$.

Answer:

D. $112 + 25m+45 = 50 + 60m$
