Answer:
The correct answer is the last option, that is,
112 + 25m + 45 = 50 + 60m
Step-by-step explanation:
We have been given that the first runner has $112 in savings, received a $45 gift from a friend, and will save $25 each month. Therefore, amount of money in the account of first running after m months will be: 112 + 45 + 25m
We have been given that the second runner has $50 in savings and will save $60 each month. Therefore, amount of money in the account of second running after m months will be: 50 + 60m
In order for amount of money to be equal in accounts of both the runners, we set up: 112 + 45 + 25m = 50 + 60m
Upon rewriting the left hand side using commutative law, we get:
112 + 25m + 45 = 50 + 60m
Therefore, we can see that the last option is the correct answer.
I hope this helped. I am sorry if you get this wrong.
