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 4 small pizzas and 4 large pizzas, the perfect amount for the 28 players going out for pizza. This week, there were 24 players going, so she ordered 4 small pizzas and 3 large pizzas, which was also just the right amount. How many people does each size of pizza feed?
