The total profit that is earned is 4512.5
<h3>How to solve for the profit that is earned</h3>
100 - q = 0
q = 100
Maximization is where q = 0
MR = mc
100 - q = 5
such that q = 95
Price would be  100 -0.5(95)
= 100 - 47.5
= 52.5
Profit earned would be 
= 95*52.5 -5*95
= 4512.5

Answer: Present value = $7200
Step-by-step explanation: Given Principal that is the original amount is $6000
Rate is 10% every fourth year
But the total period is eight.
So the interest would be paid 8/4 = 2 times.
Therefore,
Simple interest 
= {principal * rate * no of times}/100
 = {$6000*10*2}/100
Simple interest = $1200
Present value 
= principal + Simple interest
= $6000 + $1200
= $7200.
 
        
             
        
        
        
Answer:
x = 12
Step-by-step explanation:
 
        
                    
             
        
        
        
Y = 3x - 8
Because y = mx + b, where m is the slope and b is the y-intercept, just substitute the two numbers.
