Optimal Solution

Question $2\mathrm{.}1$

According to the output:

number of Deluxe frames $=$

number of Professional frames $=$

Objective function value $=$

Range of Optimality

Question $2\mathrm{.}2$

Suppose the profit on deluxe frames is increased to $$20.$ Is the above solution still optimal? What is the value of the objective function when this unit profit is increased to $$20?$

Question $2\mathrm{.}3$

If the unit profit on deluxe frames were $$6$ instead of $$10,$ would the optimal solution change?
