this has todo with sells and markup rates

**$85.50**

The price of the final price of the item is the original price added to the price markup.

In other words:

Final Price = Original Price + Original Price*0.50

This can be reduced to:

Final Price = Original Price*( 1 + 0.50 ) = Original Price*( 1.50 )

So: Final Price = $57*(1.50) = $85.50

**The Final Price is 150% of the Original Price.**
