Part IV. We now have all of the information we need to solve the linear
programming problem.
1. Write an objective function for candle sales. (Hint: Think about how each TV ad
and each magazine ad affects sales.)
2. Substitute the coordinates of the corner points of the feasible region into the
objective function.
