Juan and his children went into a movie theater and he bought $52.50 worth of bags of popcorn and pretzels. Each bag of popcorn costs $7.50 and each pretzel costs
$3.75. He bought 5 more pretzels than bags of popcorn. Graphically solve a system of
equations in order to determine the number of bags of popcorn, s, and the number of
pretzels, y,
that Juan bought.
