a cable tv company charges $39 a month plus an initial setup fee one customer paid $150 total after a 3 months of service

Question

A. what is the initial set-up fee?

B. Write an equation that you could use to find the amount you pay based on how many months you have cable TV.

C. How much will you have paid after 6 months of service?

Answer 1

a. Let x = setup fee

39(3)+x=150

117+x=150

Subtract 117 from both sides

117+x-117=150-117

x=33 is the setup fee

b. Total cost = 39(m)+33 (m is the number of months of service)

c. 39(6)+33 = $267
