Choose the correct symbol for interval notation when a value is to be included in the solution
A. Parenthesis
ex
you had 
x3 when x=8
it will be 
(8)3
        
                    
             
        
        
        
Add -7y and divide both sides to get one solution (0.20588)

Answer:
2.80
Step-by-step explanation:
The discount is the regular price times the discount
discount = 19 *15%
discount = 2.85
The new price is the regular price minus the discount
new price = 19-2.85
                  =16.15
Now she has to pay the sales tax
tax = new price * tax rate
tax= 16.15 * 6.5%
      = 16.15 *.065
        =1.05
We add the tax to the new price to get the final price
final price = new price+tax
                 = 16.15 +1.05
                 =17.20
She pays with a 20 dollar bill
Change = payment - final price
               =20.00 - 17.20
               = 2.80
