Joseph and his children went into a movie theater where they sell bags of popcorn for $7.50 each and pretzels for $4.75 each. Joseph has $95

altogether. If x represents the number of bags of popcorn purchased
and y represents the number of pretzels purchased, write and solve a
system of inequalities graphically and determine one possible solution.
