Let Wa,Wb,Aa and Ab be the pounds of wheat and alfalfa used to produce feed sold at discount price.

Let W1,W2,A1 and A2 be the pounds of wheat and alfalfa used to produce feed sold at non-discounted price.

The objective is to maximize Feedco’s profit.

Profit = (cost/lb) (pounds of wheat and alfalfa feed 1 sold at non-discounted price) + (cost/lb) (pounds of wheat and alfalfa feed 2 sold at non-discounted price) + (cost/lb) (pounds of wheat and alfalfa feed 1 sold at discounted price) + (cost/lb) (pounds of wheat and alfalfa feed 2 sold at discounted price) – (cost/lb) (total pounds of wheat purchased) – (cost/lb) (total pounds of alfalfa purchased)

Profit= 1.5(W1+A1)+1.3(W2+A2)+1.25(Wa+Aa)+1(Wb+Ab)−0.5(W1+W2+Wa+Wb)−0.4(A1+A2+Aa+Ab)

Thus, the objective function is,

Maximize

z= 1.5(W1+A1)+1.3(W2+A2)+1.25(Wa+Aa)+1(Wb+Ab)−0.5(W1+W2+Wa+Wb)−0.4(A1+A2+Aa+Ab)

The following constraints are,

Constraints 1: At most, 300lb of feed 1 can be sold.

(Pounds of wheat produce feed 1) + (Pounds of alfalfa produce feed 1) ≤300

Wa+Aa≤300

Constraint 2: At most, 300lb of feed 1 can be sold.

(Pounds of wheat produce feed 2) + (Pounds of alfalfa produce feed 2) ≤300

Wb+Ab≤300

Constraint 3: At most, 1000lb of wheat can be purchased.

(Pounds of wheat used to produce feed 1) + (Pounds of wheat used to produce feed 2) ≤1000

W1+W2+Wa+Wb≤1000

Constraint 4: At most, 800lb of alfalfa can be purchased

A call center has 60 employees on‐line, each of whom make one phone call every 3 min on average, and talk on average for 2 min. Each call costs 15¢. What is the total traffic in erlangs? How many circuits are required for a GoS of 1%? How much should the yearly (250 working days, 8 working hours a day) lease price be for the company to make a 50% saving in its telephone bills over the first 3 years? Assume the lease set‐up fee of $30,000 should be paid over a period of 3 years.

Consider the following model of trade between Home and Foreign. Assume throughout that those two countries are the only two countries in the world, at least for purposes of trade. There are two goods: Corn and Radio. Consumers always spend one-third of their income on Corn and the remainder on Radios. The only factor of production is labour. Each home country worker can produce 2 units of Corn or 3 units of Radios per unit of time, while each foreign worker can produce 2 units of Corn or 4 units of Radios per unit of time. There are 30 workers in Home and 60 workers in Foreign. Draw the production possibility frontier for each country (put Corn on the vertical axis and Radios on the horizontal axis).
