Show all work. i.e., justify your answers.

Exercise 7.1 in the textbook. Note of clarification:

- The exercise instructs you to “identify the optimal solution”.
- A solution consists of two parts. Be sure to report both parts:
- 1. the values of the variables, and
- 2. the value of the objective function.

Exercise 7.2 in the textbook. Notes of clarification:

- New York consumes AT LEAST 10 shnupells, and California consumes AT LEAST 13 shnupells.
- Kansas produces AT MOST 15 shnupells, and Mexico produces AT MOST 8 shnupells.
- This makes sense since you can always eat more than you need, but will starve if you eat less than you need.
- Similarly a factory can always produce less than its max capacity but cannot produce more.
- The exercise instructs you to “write a linear program”.
- Writing a linear program is about formulating the problem into mathematical (algebraic) form. The algebraic form has three important ingredients. Be sure to report all three parts:
- 1. the variables and their meanings
- 2. the objective function (in terms of the variables)
- 3. the constraints (also in terms of the variables)
