Step-by-step explanation:
To find the original purchase price, write a proportion and solve. A proportion is an equation where two ratios are set equal.
If the discount if 15% then you pay 85%.

To solve for y, cross multiply the numerator and denominator of each fraction.

3672= 85y
43.2 = y
 
        
             
        
        
        
Example 2x + y =3 
 -2x -2x 
—————————————— 
 Y = 3 - 2x or y = -2x - 3
