To write a linear equation to represent this model, we need to determine the relationship between the total cost (y) and the number of months (x).
The installation fee of $175 is a one-time charge, so it does not depend on the number of months. Therefore, it can be considered a constant in our equation.
The monthly access charge of $39.95 is multiplied by the number of months (x), as it will be charged every month. Therefore, it is variable and we will multiply it by x in our equation.
Thus, the linear equation to represent this model is:
y = 175 + 39.95x
A high-speed internet company charges $175 installation fee and a monthly access charge of $39.95. Write a linear equation to represent this model.
