50-x product B is 9x4 (50-x) ≤ 3603x10 (50-x) ≤ 290 according to the meaning of the question.
The solution is 30≤x≤32.
X is an integer.
∴ Only 30,365,438+0,32 can be taken, and the corresponding values are 20,654,38+09,654,38+08.
∴ There are three production schemes:
Scheme 1: 30 products and 20 products;
The second scheme: 3 1 product and 19 product;
Scheme 3: 32 products, 18 products.
