a.

Explanation of Solution

Optimal solution

• From the LINDO output, the allowable decrease for Brownies is within the range.
• As a result, the decision variables remain unchanged...

b.

Explanation of Solution

Optimal solution

• If a bottle of cola cost 35, then from the LINDO output the allowable increase of brownies is within the range.
• Hence the current basis remains optimal.
• Hence the $\text{new cost =x}$

c.

Explanation of Solution

Cost of optimal diet

• The new optimum solution value or profit is calculated by the given formula:

  $\text{New value = Old value – }\left(\text{Key column value × Key row value}\right)\text{ / Key value}$

d.

Explanation of Solution

Cost of optimal diet

• The new optimum solution value or profit is calculated by the given formula:

  $\text{New value = Old value – }\left(\text{Key column value × Key row value}\right)\text{ / Key value}$

• The key row value can be calculated by the given

e.

Explanation of Solution

Cost of optimal diet

• The new optimum solution value or profit is calculated by the given formula:

  $\text{New value = Old value – }\left(\text{Key column value × Key row value}\right)\text{ / Key value}$

• The key row value can be calculated by the given formula:

  $\text{ Key r}$

f.

Explanation of Solution

Optimal price

• From the LINDO output, the reduced cost of pineapple cheesecake is 50...

g.

Explanation of Solution
