Question

In order to join a movie rental service, there is an initial $60 fee, then a $5 fee every month. Write an equation in slope-intercept form modeling this situation, then use it to find out how much you will have paid after 10 months of this service.

Answer 1

after 10 months of this service, you will have paid $110.

Explanation:

The equation in slope-intercept form that models this situation is:

y = mx + b

where y represents the total cost, x represents the number of months, m represents the monthly fee, and b represents the initial fee. In this case, the initial fee is $60 and the monthly fee is $5, so we have:

y = 5x + 60

To find out how much you will have paid after 10 months, we can substitute x = 10 into the equation:

y = 5(10) + 60

y = 50 + 60

y = 110

Therefore, after 10 months of this service, you will have paid $110.
