zlopas [31]

Answer:

M + W <= 40

M >= 12

M >= 15

Total profit =  $26 * M + $14 * W

Step-by-step explanation:

Let the number of men be denoted by M

number of women be denoted by W

Maximum no of people that can go one trip = 40

Therefore representing it mathematically we have

M + W <= 40  -------------- CONSTRAINT 1

Minimum number of men needed on trip = 12

Therefore representing it mathematically we have

M >= 12  CONSTRAINT 2

Minimum number of women needed on trip = 15

Therefore representing it mathematically we have

M >= 15  CONSTRAINT  3

profit on 1 man = $26

profit on M men = $26 * M

profit on 1 woman = $14

profit on M men = $14 * W

Total profit combining for men and women =

 $26 * M + $14 * W  -------------CONSTRAINT  4

___________________________________________

writing together all the constraint

M + W <= 40

M >= 12

M >= 15

Total profit =  $26 * M + $14 * W
