Answer:
Last Year Now
Units Produced 1,200 1,200
Labor (hours) 300 250
Resin (pounds) 50 46
Capital Invested ($) 9,000 11,000
Energy (BTU) 2,950 2,850
last year's labor productivity = 1,200 / 300 = 4 units per labor hour
current year's labor productivity = 1,200 / 250 = 4.8 units per labor hour
productivity increased by (4.8 - 4) / 4 = 20%
last year's materials productivity = 1,200 / 50 = 24 units per pound of resin
current year's materials productivity = 1,200 / 46 = 26.09 units per pound of resin
productivity increased by (26.09 - 24) / 24 = 8.7%
last year's capital productivity = 1,200 / 9,000 = 0.1333 units per $ invested
current year's capital productivity = 1,200 / 11,000 = 0.1091 units per $ invested
productivity decreased by (0.1091 - 0.1333) / 0.1333 = -18.18%
last year's energy productivity = 1,200 / 2,950 = 0.4068 units per BTU
current year's energy productivity = 1,200 / 2,850 = 0.4211 units per BTU
productivity increased by (0.4211 - 0.4068) / 0.4068 = 3.52%
