You are buying 10 pizzas for a party. Cheese pizza cost $11 each, and single topping pizzas cost $13 each. Write an equation that gives the total cost, C, (In dollars) as a function of the number, P, of cheese pizzas that you buy. Then find the total cost if you buy 4 cheese pizzas.
Anyone care to translate that?

Respuesta :

Yes, that would be...
the equation would be...
first,  p = cheese pizza
         s = single topping pizzas
         c = total cost

11p + 13s = c

plug in number of cheese pizzas into equation!
