Question 785084: I don't understand if I am doing the correct equation
Problem: You are buying 10 pizzas for a party. Cheese pizzas 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
This is what I have come up with:
C(x)= 11x-13 I am confused. Please and thank you.

Your question only asks about the cheese pizzas. One thing you need to learn is to use the needed information and ignore the unrelated information.

Cost for p cheese pizzas, highlight%28C%28p%29=11p%29.
Four cheese pizzas will cost highlight%28C%284%29=11%2A4=44%29 dollars.
