A phone company has a monthly cellular plan where a customer pays a flat monthly fee and thena certain amount of money per minute used on thephone. If a customer uses 410 minutes, the monthly cost will be $71.50. If the customer uses 720 minutes,the monthly cost will be $118.
a. Find a linear equation for the monthly cost of thecell plan as a
b. Interpret the slope and y-intercept of the equation.
c. Use your equation to find the total monthly cost if687 minutes are used.
