The Chess Club ordered 10 pizzas and 5 dozen chicken wings, which came to a total of $100. At the same time, the Spanish Club ordered 12 pizzas and 4 dozen chicken wings for a total of $108. Let x = the cost of a pizza and y = the cost of a dozen chicken wings. Write a system of equations that would enable you to solve how much each item costs. DO NOT solve for the prices. Just write the system of equations.
