Question

During a football game, the parents of the football players sell pretzels and popcorn to raise money for new uniforms. They charge $2.50 for a bag of popcorn and $2 for a pretzel. The parents collect $336 in sales during the game. They sell twice as many bags of popcorn as pretzels. How many bags of popcorn and pretzels do they sell?

Answer 1

2.5x + 2y = 336

x = 2y

2 equations, 2 unknowns, solvable

3.5x = 336

7x = 672

x = 672 / 7

x = 96

96 / 2 = y

y = 48

they sold 96 popcorn bags and 48 pretzels
