Write constraints & objective for this LP:

A sporting goods manufacturer produces skateboards and in­line skates.­ Its dealers demand at least 30 skateboards per day and 20 pairs of in­line skates per day.­ The factory can make at most 60 skateboards and 40 pairs of in­line skates per day.­ The total number of skateboards and pairs of in­line skates cannot exceed 90.­ The profit on each skateboard is $12 and on each pair of in­line skates is $18.

Test topics:1) Solving one­variable inequalities­ graph on a number line­ reverse the inequality symbol when multiplying or dividing by a negative

2) Solving non­linear systems of equations­ substitution is usually best, OR­ graph (first solve for y) and find intersection(s) on calculator

3) Solving two­variable systems of inequalities­ graph on an x­y plane­ shade to find region that is feasible for both / all inequalities­ dotted line vs. solid line, reverse the inequality symbol when multiplying or dividing by a negative number

4) Calculating maximum / minimum objectives given constraints­ find (use systems of equations if needed) and evaluate vertex points ­ profit is always maximized, cost is always minimized

5) Identifying constraints given a feasible region­ each border is typically a separate constraint

6) Linear programming­ identify variables­ write constraints (inequalities) and objective function­ graph only the constraints (not the objective!)­ identify the feasible region / find the vertices (use systems of equations if needed)­ test the vertices in the objective function
