The right answer is: d.112 + 25m + 45 = 50 + 60m
Step-by-step explanation:
Let m be the number of months
<u>For First Runner:</u>
He already has 112 in savings and got 45 from a friend so these will be constant values and as he will be saving $25 each month so
<u>For Second Runner:</u>
He already has $50 in saving and ill save 60 each month so
In order to find that when there accounts will have same amount, the expressions for both will be put equal
The value of m will give us the number of months after which the accounts of both runners will have same amount.
Hence,
The right answer is: d.112 + 25m + 45 = 50 + 60m
