An engineering team wants to recruit Class A and Class B workers 150, and the monthly wages of Class A and Class B workers should be 600 yuan and 1 000 yuan respectively.

Solution: Set position B to recruit X people.

x≥2( 150-x)

∴x≥ 100

W[ salary] = 600 (150-x)+1000x = 400x+90000.

∵400 & gt; 0,

∴x= 100, w [salary] at least = 400x100+90000 =130000 (yuan).

When Party A and Party B recruit 50 workers and 100 workers respectively, the monthly salary paid shall be at least130,000 yuan.
