Answer:

Step-by-step explanation:
Given


Required
Possible values of k
The general quadratic equation is:

Subtract  and
 and 


Factorize:

Rewrite as:

Compare the above equation to: 



For the equation to have two distinct solution, the following must be true:

So, we have:

 
Expand

Rewrite as:


Expand

Factorize

Factor out k + 6

Split:
 or
 or 
So:
 or k
 or k 
To make the above inequality true, we set:
 or
 or 
So, the set of values of k is:

 
        
             
        
        
        
The answer is a 40% discount because it costs $24 less than the original price and 24 divided by 60 is .4 or 40%!
