Combining functions to write a new function that models a real-world... A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven. The standard charge \( S \) (in dollars) is given by tl function \( S=0.40 M+15.75 \), where \( M \) is the number of miles driven. The company also offers an option to insure the car against damage. The insurance charge \( I \) (in dollars) is given by the function \( I=0.15 M+5.70 \). Let 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.
