Johnson manufacturing has a division that produces two models of fireplace grates, model K and model L. To produce each model K grate requires 3 pounds of cast iron and 6 minutes of labor. To produce each model L grate requires 4 pounds of cast iron and 3 minutes of labor. The profit for each model K grate is $2.00, and the profit for each model L grate is $1.50. If 1000 pounds of cast iron and 20 hours of labor are available for the production of grates per day, how many grates of each model should the division produce per day to maximize Johnson's profits? Interpret your result.
