Sharon wants to switch from cable to satellite TV. She calls Great Vista Satellite to get a quote. After looking at her cable bill, the salesperson explains that they can provide the same 300 channels Sharon has for $0.20 less per channel. If she switches, her monthly satellite bill will come to $180

Using proportions, it is found that her satellite bill before the switch was of $240.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, she can pay a total of $180 per 300 channels, hence her price per channel will be of:

p = 180/300 = $0.6.

She currently pays $0.2 more, that is, $0.8, hence:

B = 300 x 0.8 = 240.

Her satellite bill before the switch was of $240.
