Question 3

The factory produces two types of products: P_1 and P_2. For the production of these products, three initial products are used - A, B, C. The maximum possible daily reserves of these products are 12, 11 and 9 tons, respectively. The costs of raw materials A, B, C per 1 thousand products P_1 and P_2 are shown in the table.


Initial product Consumption of initial products per 1 thousand items (t) Maximum possible stock (t)

P_1 P_2

A 2 4 12

B 3 5 11

S 4 7 9



The daily demand for products P_1 never exceeds the demand for products P_2 by more than 2 thousand pieces. In addition, it has been established that the demand for products P_1 never exceeds 3 thousand pieces. per day.

Wholesale prices 1 thousand pieces. products P_1 are equal to 2,7 thousand rubles, 1 thousand pieces. P_2 - 2,9 thousand rubles.

X_1 - daily production volume of the product П_1в thousand pieces; X_2 - daily production volume of item P_2 in thousand pieces.
