A hand-drill manufacturer that produces two models, regular and portable, must assemble at least 100 drills for each day’s delivery. The regular drill requires 2 hrs of preparation and costs $10 and the portable requires 5 hrs of preparation and costs $15. The dealer’s objective is to minimize his total cost of preparation given that he has 400 preparation hrs available each day and at least 40 portables must be assembled each day.
