Question

You are looking for a new cell phone plan. The first company, Cellular-Tastic (f), charges a

monthly fee of $35 and $0.11 per minute of use. Dirt-Cheap Cell (g) charges a monthly fee
of $55 and $0.01 per minute of use.
1. How many minutes would you need to use for the cell phones to cost the same
amount?

Answer 1

200 minutes

Explanation:

Given that:

Cellular - Tastic (f) :

Monthly fee = $35

Per minute fee = $0.11

Dirt cheap call (g) :

Monthly fee = $55

Per minute fee = $0.01

How many minutes would you need to use for the cell phones to cost the same

amount?

Let number of minutes for cost to be equal = x

35 + 0.11x = 55 + 0.01x

Collect like terms

0.11x - 0.01x = 55 - 35

0.1x = 20

x = 20/0.1

x = 200

Hence, for cost to be the Same, 200 minutes must be used
