Isolate the radical:

Square both sides:

Expand using FOIL and  :
:

Move everything to one side to get a quadratic:

Solving using the quadratic formula:
A quadratic in  has real solutions
 has real solutions  . In
. In  , assign values:
, assign values:

Solving yields:

Only  works when plugged in the original equation. Therefore,
 works when plugged in the original equation. Therefore,  is extraneous and the only solution is
 is extraneous and the only solution is 
 
        
             
        
        
        
0.75 x 14 = 10.50
15 - 10.50 = 4.50 
your answer is : Sharon will receive $4.50 change
