Rewrite in standard form and use the form to find the vertex. 
(1, 5) 
(x - 1)^2 + 5
 
        
             
        
        
        
Answer:
Dori has $48 left.
Step-by-step explanation:
The boat costs twice as much as the goggles, divide 8 by 2 to find the price of the goggles. The price of the goggles is $4. 
Add $8 and $4 to get $12. This is the total money Dori spent. 
Since this is 1/5 of her money, multiply $12 by 5 to get $60. This is the money Dori had. 
Subtract the $12 from the $60 to get $48. This is the money Dori has left.
