Chapter 5.2, Problem 3P

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 new cost =x

c.

Explanation of Solution

Cost of optimal diet

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

    New value = Old value – (Key column value × Key row value) / Key value

d.

Explanation of Solution

Cost of optimal diet

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

    New value = Old value – (Key column value × Key row value) / 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:

    New value = Old value – (Key column value × Key row value) / Key value

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

     Key r

f.

Explanation of Solution

Optimal price

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

g.

Explanation of Solution
