The correct equation to represent the total amount paid for the internet service after a certain number of months is 'Total amount = 48 * number of months + 137'. We found this by substituting given values into the general equation and solving for the setup fee.
The subject of your question is related to solving for cost over time or simple algebraic word problems in Mathematics. The equation that represents the given problem is Total amount = 48 * x + initial setup fee, where x represents the number of months. We know from the question that after 8 months, $449 has been paid, and we know the monthly charge is $48. Therefore, we can substitute these values into the equation to get $449 = 48 * 8 + setup fee. By simplifying, we find that the setup fee is $137. Adding a setup fee to the product of the monthly fee and the number of months provides the total amount paid. Therefore the correct answer to this problem is: Total amount = 48 * number months + 137.of
