Question

Your local cable television company offers two plans: basic service with one movie channel for $35 per month or basic service with two movie channels for $45 per month. What is the change for the basic service and the change for each movie channel?

Answer 1

Each movie = $10

Basic = $25

Explanation:

Let M represent Movie

B represent Basic

Given that

M + B = 35. Equation 1

2M + B = 45. Equation 2

Making B the subject of formula in equation 1

B = 35 - M. Equation 3

Put equation 3 into 2

We have

2M + (35 - M) = 45

2M - M = 45 - 35

M = 10.

Therefore is movie charges $10

Recall that

B = 35 - M

B = 35 - 10

B = 25

Therefore, Basic charges $25
