Question:the carpentry shop makes bookcases and cabinets. each bookcase requires 15 hours of woodworking and 9 hours of finishing. the cabinets require 10 hours of woodworking and 4.5 hours of finishing. the profit is 60 dollars on each bookcase and 40 dollars on each cabinet. there are 70 hours available each week for woodworking and 36 hours available for finishing. how many of each item should be produced in order to maximize profit?
what are the inequalities.
Answers:Start by organizing your information mathematically: $60=B=15W+9F $40=C=10W+4.5F 15W+9F+10W+4.5F=$100 25W+13.5F=$100 25W = 10013.5F 36 (less than or equal to) F 70 (less than or equal to) W Profit is maximized at 7 cabinets and no bookcases.
