Taizhou Jiaojiang is known as the "embroidery capital of China", and its products sell well all over the world. A manufacturing enterprise wants to transport N products to A, B and C for sale.

(1)① Fill in the form according to the information:

;

② According to the meaning of the question, 200-3x ≤ 2x130x+1600-24x+50x ≤ 4000②,

If inequality ① is solved, x≥40,

If inequality ② is solved, x≤42 6 7,

Therefore, 40≤x≤42 6 7,

∵x is an integer,

∴x=40 or 4 1 or 42,

∴ There are three schemes, namely: Scheme 1: 40 in A, 80 in B and 80 in C;

Scheme 2: A site 465,438+0, B site 77 and C site 82;

Scheme 3: 42 stations A, 74 stations B and 84 stations C;

(2) From the meaning of the question, we get 30x+8(n-3x)+50x=5800.

Finishing, n=725-7x,

∫n-3x≥0，

∴725-7x-3x≥0，

The solution is x≤72.5,

And ∵x≥0,

∴0≤x≤72.5 and x are integers,

∫n decreases with the increase of x,

When x=72, the minimum value of n is 725-7× 72 = 22 1.
