The value of x is 2x+38=90
The answer is x=26
Answer:
a. x1,x2,x3,x4
b. 20x1 + 24x2 + 28x3
c. x1 +x2 ≥ 25
Step-by-step explanation:
At a time that spans from 1 to 5pm, we have timing as follows:
1pm - 2pm = x1
2pm - 3pm = x2
3pm - 4pm = x3
4pm - 5pm = x4
a. The decision variables are x1, x2, x3, x4 and these are the number of people for each shift.
b. The objective function is the minimum cost which is
20x1 + 24x2 + 28x3
c. The constraints for each has been listed
1 - 2pm, x1 ≥ 20 workers
2 - 3pm, x1 + x2 ≥ 25
3 - 4pm, x2 + x3 ≥ 25
4 - 5pm, x3 ≥ 30
The question asked us to write the one for 2-3pm, which is x1 + x2 ≥ 25
Answer:
x - 3/7
