Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
Knowing this, we should start by doing the equations <em>within </em>each parentheses. 
 
 
So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:

20 is the answer.

Answer: B= A/(C+D)
Step-by-step explanation:
A = B(C+D)
Divide each side by B
A/B= C+D
Reciprocate both sides
B/A = 1/(C+D)
Now multiply each side by A
B = A/(C+D)
 
        
                    
             
        
        
        
1. If a shift in demand and/or supply has taken place, identify the change and list the determinant.
Answer:
The answer is below
Step-by-step explanation:
The demand has increased or shifted to the right. 
The supply did not change.
The determinant for this situation is the increase in demand
However, with the price increment, the will be an increase in supply.
