Verified step by step guidance

1. Identify the original price and the new price of the smartphone. Here, the original price is \$800 and the new price is \$680.
2. Calculate the amount of price decrease by subtracting the new price from the original price: \(\$800 - \$680\).
3. Find the percent decrease by dividing the price decrease by the original price: \(\frac{\text{Price Decrease}}{\text{Original Price}}\).
4. Convert the fraction to a percentage by multiplying the result by 100: \(\left( \frac{\text{Price Decrease}}{\text{Original Price}} \right) \times 100\).
5. Interpret the result as the percent decrease in price, which tells you how much the price has dropped relative to the original price.
