Answer:
The month in which both have to pay the same total amount is:
5th month.
Explanation:
Let the month be x where we have to pay the same total amount for the internet service.
i.e. the total amount for Company A in x months is:
60+42.95x
and the total amount for Company B in x months is:
25+49.95x
The total amount is same for both the companies i.e. we have the equation as follows:
60+42.95x = 25+49.95x
On solving by combining the like terms we have:
![49.95x-42.95x=60-25\\\\7x=35\\\\x=(35)/(7)\\\\x=5](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ebfpw993a433d95abpotkmjjpl6k1afcje.png)
