Homework 1-Solution Chapter 2 4. (2 points) Productivity at facility 1 = 240 chairs/6 workers = 40 chairs per worker Productivity at facility 2 = 210 chairs/4 workers = 52.5 chairs per worker Facility 2 is more productive. 6. (2 points) Using only the non-defective production, productivity has increased from (60-10)=50 pieces per day to (90-1)=89 pieces per day. Change in productivity = (89-50)/50 x 100% = 78% increase Or (60-10)/8=6.25 pieces per hour (90-1)/8=11.125 pieces per hour Change in productivity=(11.125-6.25)/6.25=0.78

    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.
