Question

an internet service provider chargers $18 per month plus an initial set up fee. One customer paid a total of $81 after 2 months. Write an equation modeling this situation on slope- intercept form.

Answer 1

y = 18x + 45

Explanation:

81 = 18x + b

81 = 18(2) + b

81 = 36 + b

b = 45 so 45$ is the initial set up fee
