Answer:

Objective function:

Maximize Z: 30P1 + 25P2 + 28P3

Subject to:   2.00P1 + 1.50P2 + 3.00P3 ≤ 450 (Department A constraint)

                    2.50P1  + 2.00P2 + P3       ≤ 350 (Department B constraint)

                    0.25P1  + 0.25P2 + 0.25P3 ≤ 50  (Department C constraint)

                           P1, P2, P3                       ≥  0 (Non-negativity)

Explanation:

The objective function is formulated from the contribution margin of the three products. For instance, the contribution of Product 1 is $30, the contribution of Product 2 is $25 and the contribution of Product 3 is $28. Thus, the objective function will be 30P1 + 25P2 + 28P3.

The constraints were obtained from the departmental labour hours requirements for each product. For instance, Product 1 requires 2 hours in department A, Product 2 requires 1.50 hours in department A and Product 3 requires 3 hours in Department A. Thus, the constraint will be 2.00P1 + 1.50P2 + 3.00P3.

borishaifa [10]

Answer:

  • Single asset = Coefficient of Variation
  • Portfolio = Beta

Explanation:

When dealing with standalone risk, coefficient of variation is best because it shows the amount by which the asset's returns might deviate from the average returns of the market.

As for portfolio assets that are well diversified, the best measure would be beta because diversified portfolios deal with systematic risk and beta shows the movement of the portfolio in relation to the market and so will show that systematic risk.

Becky only eats out at Macaroni Grill and eats out three times per month. She receives a raise from $33,200 to $33,500 and decid
iragen [17]

Answer:

55.58

Explanation:

Data provided in the question;

Initial demand per month, Q₁ = 3

Final demand per month, Q₂ = 5

Initial price, P₁ = $33,200

Final price, P₂ = $33,500

Now,

elasticity of demand using midpoint method is calculated as :

= \frac{\textup{percent change in demand}}{\textup{percent change in supply}}

or

= \frac{\frac{Q_2-Q_1}{\frac{Q_1+Q_2}{2}}}{\frac{P_2-P_1}{\frac{P_1+P_2}{2}}}

on substituting the respective values, we get

= \frac{\frac{5-3}{\frac{5+3}{2}}}{\frac{33,500-33,200}{\frac{33,200+33,500}{2}}}

or

= \frac{\frac{2}{4}}{\frac{300}{\frac{66,700}{2}}}

or

= \frac{0.5}{\frac{300}{33,350}}

= 55.58
