The Apple Company makes iPods and iPads. iPods require 3 hours in assembly and 1 hour in finishing. iPads require 4 hours in assembly and 2 hours in finishing. The assembly department is open for less than 100 hours per week and the finishing department is open for less than 50 hours per week. Let x = the number of iPods created and let y = the number of iPads created. This inequality represents the assembly constraint in this linear programming problem.
