In a diet problem one seeks to minimize the cost of meeting dietary

requirements for four nutrients, $A,B,C,$ and $D.$ There are five possible food

components, numbered $1$ through $5$ that are used to achieve this goal. The

problem has been modeled and optimized. The sensitivity report is shown

below:

Variable Cells

Constraints

The above Sensitivity Report indicates that

Increasing the cost of Component $4$ by $$0\mathrm{.}25$ per unit will have no effect on the

optimal solution.

Increasing the cost of Component $4$ by $$0\mathrm{.}25$ per unit will have no effect on the

optimal solution value.

Increasing the cost of Component $1$ by $$0\mathrm{.}50$ per unit will have no effect on the

optimal solution.

Increasing the cost of Component $1$ to $$0\mathrm{.}50$ per unit will have no effect on the

optimal solution value.

Exactly two answers are correct.

Exactly three answers are correct.
