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.

Accepted Solution

A:
Answer:200 minutesStep-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)
