Red Star Company wants to recruit 150 people for two jobs, A and B. The monthly wages of the workers for the two jobs are 600 and 1 000 respectively, and B workers are needed.

Because the number of people in B is not less than twice that of A, let's assume that the number of people in B is twice that of A, then the number of people in B should be150/(1+2) * 2 =100, and the number of people in A is 50, so the monthly salary paid at this time should be 50 * 600+65438. So if the number of people in B is 10 1 and the number of people in A is 49, the monthly salary payable at this time is: 49 * 600+101*1000 =130400, then according to Suppose there are workers who are recruited by A and workers who are recruited by B, then the question means: A+B =150 (1) b > =2a (2) from ( 1)，a+b = 150 a = 150-b from(2):b >； = 2a b & gt= 2 *( 150-b)b & gt； = 300-2 * b b+ 2 * b & gt； = 300 3 * b>= 300 b>= 100 and monthly salary = 600 * a+1 000 * b = 600 * a+600 * b+400 * b = 600 * (a+b)+4000.
