Please I need help asap! A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven. The standard charge (in dollars) is given by the function s=14.95+0.40M, where m is the number of miles driven. The company also offers an option to insure the car against damage. The insurance charge (in dollars) is given by the function i=5.80+0.25M. Let c be the total charge (in dollars) for a rental that includes insurance. Write an equation relating c to m. Simplify your answer as much as possible.
