of certainty, risk or uncertainty. Explain your answer.
A. A farmer from must decide how many acres of land he should use to allocate corn, and how many - for soy. 
B. When the weather is hot there is a great demand for ice cream at the baseball stadium and sausages are sold much worse. In cold weather, things are changing. Sanitary rules do not allow you to store ice cream or sausages for more than two days. Due to the large volume of orders suppliers require sellers to apply for the products not later than within seven days, otherwise they do not guarantee delivery. Determine how much ice cream and sausages should be ordered from the organizer of the trade for a big game next week.
C. Standard of quality of the pet food stipulates the minimum amount of proteins, fats and carbohydrates and the maximum amount of ballast components of the final mixture. There are three main components to produce feed mixtures with different proportions of proteins, fats and carbohydrates. The price of the components is different. Manufacturer of feed mixtures wants to satisfy the requirements of the standard at minimum cost. Determine the appropriate proportions of the main components of the mixture.

the monopolist, as well as the maximum profit if the total cost function has the form:
TC = 200 + 60Q + 1,5Q2.
The demand function for the products of monopoly:
Q = 240 – 2P.
Why Q is not the same as when finding the maximum profit and maximum revenue?

- 0,5 × P and the total cost function TC = 1500 + 40 x Q + Q2.
Find the volume of the production for maximum profit.

0,25Q2 can sell products in the domestic market, the demand for which displays the function
D = 60 – P1, and on the world market at price P2 = 30.
Determine the volume of sales in both markets, the price in the domestic market and the profit of the monopoly
