Hiro and Lisa are photographers. They take pictures of seniors for high school yearbooks. They charge a standard fee for taking pictures. There's also a charge for each set of prints ordered. So the number of sets of prints determines the total cost . Set of prints Total cost 0 $15 1 $18 2 $21 3 $24 Let s stand for the sets of prints ordered. Write the rule that describes a students total cost.
