A manufacturing company makes two types of waterskis, a trick ski and a slalom ski. The trick ski requires 8 labor-hours for fabricating and 1 labor-hour for finishing. The slalom ski requires 3 labor-hours for fabricating and 1 labor-hour for finishing. The maximumlabor-hours available per day for fabricating and finishing are 72 and 20 respectively. Find the set of feasible solutions graphically for the number of each type of ski that can be produced.

If x is the number of trick skis and y is the number of slalom skis produced perday, what would be the system of linear inequalities that indicates appropriate restraints on x and y.

What are the inequalities for the constraint on fabricating time.
