A baby products company makes car seats, strollers, and travel yards. A particular model of car seat requires 5 labor-hours for parts creation, 4 labor-hours for assembly, and 2 labor-hours for finishing and packaging. A particular model of stroller requires 3 labor-hours for parts creation, 3 labor-hours for assembly, and 1 labor-hour for finishing and packaging. A particular model of travel yard requires 2 labor-hours for parts creation, 3 labor-hours for assembly, and 1 labor-hour for finishing and packaging. There are 450 labor-hours available for parts creation, 380 for assembly, and 140 for finishing and packaging. If the profit per car seat is $30, per stroller is $10, and per travel yard is $18, how many of each should be produced to maximize profit? What advice would you give this company?
