My cell phone company charges \( \$ 49 \) per month plus \( \$ 0.10 \) per minute for long distance calls. Write an equation that represents the total cost \( C \) for \( x \) minutes of long distance calls. How many minutes of long distance calls can I make and stay within my limit of \( \$ 80 \) ? Find the \( x \) - and \( y \)-intercepts for the line \[ -2 x+5 y=22 \] Show all work and check your answer.

Quick Answer

The equation for total cost is \( C = 49 + 0.10x \). To stay within \( \$80 \), you can make up to 310 minutes of long distance calls. The \( x \)-intercept is \( (-11, 0) \) and the \( y \)-intercept is \( (0, 4.4) \).
