Step-by-step explanation:
Given
![Sales\ Price = \$209.99](https://tex.z-dn.net/?f=Sales%5C%20Price%20%3D%20%5C%24209.99)
![Saved = \$20.00](https://tex.z-dn.net/?f=Saved%20%3D%20%5C%2420.00)
Required
Determine the %decrease
First, we need to determine the amount paid
![Amount = Sales\ Price - Amount\ Saved](https://tex.z-dn.net/?f=Amount%20%3D%20Sales%5C%20Price%20-%20Amount%5C%20Saved)
![Amount = \$209.99 - \$20.00](https://tex.z-dn.net/?f=Amount%20%3D%20%5C%24209.99%20-%20%5C%2420.00)
![Amount = \$189.99](https://tex.z-dn.net/?f=Amount%20%3D%20%5C%24189.99)
The percentage decrease is the calculated as follows:
![\%\ decrease = -100\% * \frac{Final - Initial}{Initial}](https://tex.z-dn.net/?f=%5C%25%5C%20decrease%20%3D%20-100%5C%25%20%2A%20%5Cfrac%7BFinal%20-%20Initial%7D%7BInitial%7D)
In this case;
![Initial = Sales\ Price = \$209.99](https://tex.z-dn.net/?f=Initial%20%3D%20Sales%5C%20Price%20%3D%20%5C%24209.99)
![Final = Amount\ Paid = \$189.99](https://tex.z-dn.net/?f=Final%20%3D%20Amount%5C%20Paid%20%3D%20%5C%24189.99)
So; we have:
![\%\ decrease = -100\% * \frac{189.99 - 209.99}{209.99}](https://tex.z-dn.net/?f=%5C%25%5C%20decrease%20%3D%20-100%5C%25%20%2A%20%5Cfrac%7B189.99%20-%20209.99%7D%7B209.99%7D)
![\%\ decrease = -100\% * \frac{-20}{209.99}](https://tex.z-dn.net/?f=%5C%25%5C%20decrease%20%3D%20-100%5C%25%20%2A%20%5Cfrac%7B-20%7D%7B209.99%7D)
![\%\ decrease = 100\% * \frac{20}{209.99}](https://tex.z-dn.net/?f=%5C%25%5C%20decrease%20%3D%20100%5C%25%20%2A%20%5Cfrac%7B20%7D%7B209.99%7D)
![\%\ decrease = \frac{2000\%}{209.99}](https://tex.z-dn.net/?f=%5C%25%5C%20decrease%20%3D%20%20%5Cfrac%7B2000%5C%25%7D%7B209.99%7D)
![\%\ decrease = 9.52426306015\%](https://tex.z-dn.net/?f=%5C%25%5C%20decrease%20%3D%20%209.52426306015%5C%25)
