Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.
A baseball coach takes her team out for pizza every time they win a game. Not everyone can come
each time, so she orders the pizzas based on how many players are coming. After last week's
victory, she bought 3 small pizzas and 2 large pizzas, the perfect amount for the 17 players going
out for pizza. This week, there were 25 players going, so she ordered 3 small pizzas and 4 large
pizzas, which was also just the right amount. How many people does each size of pizza feed?
Each small pizza feeds
people, and each large pizza feeds
people.
