The Math Club sold slices of pizza, p, at a profit of $4 each and cans of soda, s, at $1 each, to raise money for a trip. They sold 300 items and made a profit of $600. Write the pair of linear equations that model this situation.
Let x be the number of pizza slices sold and y be the number of cans of soda sold.
1. The total number of items sold is 300:
x + y = 300
2. Profit from pizza slices is $4 each and profit from cans of soda is $1 each, with a total profit of $600:
4x + y = 600
