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.
