You are thinking of making your home more energy efficient by replacing some of the light bulbs with compact fluorescent bulbs and insulating part all of your exterior walls. Each compact fluorescent light bulb costs $4 and saves you an average of $2 per year in energy costs, and each square foom of wall insulation costs $1 and saves you an average of $0.20 per year in energy costs. Your home has 70 light fittings and 1,100 square feet of uninsulated exterior wall. You can spend no more than $1,200 and would like to save as much per year in energy costs as possible. How many compact fluorescent light bulbs and how many square feet of insulation should you purchase? How much will you save in energy costs per year? Let x = number of compact fluorescent light bulbs, let y = number of square feet of insulation, and let s = cost savings (in dollars). Determine the objective and the constraints needed to solve the problem. Objective maximize S= Constraints 4.00x + 1.00y ≤ 1,200 XS ys x ≥ 0, y 20 You are thinking of making your home more energy efficient by replacing some of the light bulbs with compact fluorescent bulbs and insulating part all of your exterior walls.
