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. How many times would you need to use for the cell phones to cost the same amount.

200 minutes

Step-by-step explanation:

Let x minutes is needed to use for the cell phones to coast the same amount.

Now, f (x) = 35 + 0.11x ... (1) {As per given conditions}

and g (x) = 55 + 0.01 x ... (2) {As per given conditions}

Now, f (x) = g (x)

so, 35 + 0.11x = 55 + 0.01x

⇒ 0.1x = 20

⇒ x = 200 minutes.

Therefore, after using 200 minutes the cost of the call will be the same for both the plans. (Answer)
