Step-by-step explanation:
From the question we are told that:
Demand point 
Supply Point 
Generally the equation for fixed-requirement constraints is mathematically given by



Therefore the correct option is
Option B
Answer:
24
Step-by-step explanation:
Given that:
Total number of members who race = 18
Ratio of racers to divers = 6 : 2
To find:
Total number of members of the team = ?
Solution:
Given the ratio = 6 : 2
As per the ratio given, we can let the number of racers = 
and
As per the ratio given, we can let the number of divers = 
As the swim team members can either race or dive, we can say that:
Total number of members on the team = Number of racers + Number of divers
Total number of members on the team = 
As per the question statement, we are given that:

Therefore, total number of team members = 8
3 = <em>24</em>
Answer:50
Step-by-step explanation:
Since the total of angles is 180, you just substract two numbers given by 180. Then, you will get 50. 180-(58+72) = 50
