We have to make a equation. So for the red company the equation is 150 + 72h where h stands for or equals to hours. We are using 150 as stand alone is because it is a one time fee and every hour your rent you pay 72 so 150 plus 72 times h where h can be any number of hours. For the blue company it's 240 + 54h where h stands for or equals to number of hours. Same as the other one 240 is stand alone and a one time fee and 54 is how much you pay every hour your rent it so it would be 240 plus 54 times h where h can be any number of hours.
