Maximizing Profil on Ice Skates A factory manufactures two kinds of ice skates: racing skates and figure skates. The racing skates require 6 work-hours in the fabrication department, whereas the figure skates require 4 work-hours there. The racing skates require 1 work-hour in the finishing department, whereas the figure skates require 2 work-hours there. The fabricating department has available at most 120 work-hours per day, and the finishing department has no more than 40 work-hours per day available. If the profit on each racing skate is and the profit on each figure skate is , how many of each should be manufactured each day to maximize profit? (Assume that all skates made are sold.)

- Manufacturing Calculators A manufacturer of calculators produces two models; standard and scientific. Long-term demand for the two models mandates that the company manufacture at least 100 standard and 80 scientific calculators each day. However, because of limitations on production capacity, no more than 200 standard and 170 scientific calculators can be made daily. To satisfy a shipping contract, A total of at least 200 calculators must be shipped every day. (a) If the production cost is $5 for a standard calculator and $7 for a scientific one, how many of each model should be produced daily to minimize this cost? (b) Id each standard calculator results in a $2 loss but each but each scientific one produces a $5 profit, how many of each model should daily to maximize profit?arrow_forwardManufacturing Calculators A manufacturer of calculators produces two models: standard and scientific.
