Answer:
100 minutes
Step-by-step explanation:
Let the number of minutes required for the two Billings to be equal be x.
Now we write this in an equation form.
7.95 + 0.05x = 9.95 + 0.03x 
0.05x - 0.03x = 9.95 - 7.95
0.02x = 2
x = 2/0.02 = 100 minutes 
At the 100th minute, the amount of Billings would be equal 
 
        
             
        
        
        
To find this answer, all we have to do is identify the least common multiple of 6 and 20
the lowest number that both of these numbers can go into evenly is 60
so each 60th visitor gets both
        
             
        
        
        
Answer:
f=2x^2+6x-20/x
Step-by-step explanation:Divide both sides by x
fx/x=2x^2+6x-20/x
f=2x^2+6x-20/x
