Jacob and his children went into a grocery store where they sell apples for $1 each
and peaches for $0.50 each. Jacob has $8.50 to spend and must buy at least 10
apples and peaches altogether. Also, he must buy no more than 8 peaches. If a
represents the number of apples purchased and y represents the number of peaches
purchased, write and solve a system of inequalities graphically and determine one
possible solution.
