Answer:
The price elasticity of demand is -10
Step-by-step explanation:
Given


Solving (a): The coefficient of price elasticity of demand (k)
This is calculated as:

So, we have:



<em>Because |k| > 0, then we can conclude that the company made a wise decision.</em>
 
        
             
        
        
        
Answer:
58
Step-by-step explanation:
6*8+2*2+3*2=58
 
        
                    
             
        
        
        
Solve for p:
p/8 + 3/8 = 25/8
p/8 + 3/8 = (p + 3)/8:
(p + 3)/8 = 25/8
Multiply both sides of (p + 3)/8 = 25/8 by 8:
(8 (p + 3))/8 = (8×25)/8
(8×25)/8 = (8×25)/8:
(8 (p + 3))/8 = (8×25)/8
(8 (p + 3))/8 = 8/8×(p + 3) = p + 3:p + 3 = (8×25)/8
(8×25)/8 = 8/8×25 = 25:
p + 3 = 25
Subtract 3 from both sides:
p + (3 - 3) = 25 - 3
3 - 3 = 0:
p = 25 - 3
25 - 3 = 22:
Answer: p = 22
