Answer:

Step-by-step explanation:

let us model the cost

let the cost be y and the number of movie channel be x

for 3 comcast

y=50+5x-----1

and for Xfinity

y=41+6.5x-------2

to solve for the number of movie channel so that the two (3 comcast and Xfinity) will pay the same, we need to equate 1 and 2

50+5x=41+6.5x

50-41=6.5x-5x

9=0.5x

x=9/0.5

x=18
