24 of 31 Summary of the optimal solution Space Rays = 320 dozen Zappers = 360 dozen Profit = $4360 This solution utilizes all the plastic and all the production hours. Total production is only 680 (not 700). A slack value (implied variable) of 20 units. Space Rays production is less than Zappers production by 40 dozen, not greater than by 350 or less.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
