Qingshen bamboo weaving, exquisite workmanship, is deeply loved by people. A businessman went to Qingshen to buy two kinds of bamboo handicrafts, A and B, and sold them back.

(1) If there are x type A handicrafts, there are 60-x type B handicrafts.

According to the meaning of the question: the total cost y =150x+80 (60-x) = 70x+4800;

(2) According to the question: 60? x≥ 14(200？ 150)x+( 100？ 80)(60? x)≥2500，

Solution: 43 13≤x≤46,

∵x is a positive integer, and the values of ∴x are 44, 45 and 46.

Scheme 1: If there are 44 A-type handicrafts, there are 16 B-type handicrafts, and the profit is (200-150) × 44+(100-80 )×16 = 250.

Scheme 2: If there are 45 A-type handicrafts, there are 15 B-type handicrafts, and the profit is (200-150) × 45+(100-80 )×15 = 2550 yuan;

Scheme 3: If there are 46 A-type handicrafts, there are 14 B-type handicrafts, and the profit is (200-150) × 46+(100-80 )×14 = 2580 yuan.
