Verified step by step guidance1
Identify the original price and the new price of the smartphone. Here, the original price is \$800 and the new price is \$680.
Calculate the amount of decrease in price by subtracting the new price from the original price: \$800 - 680$.
Use the formula for percent decrease: \(\text{Percent Decrease} = \left( \frac{\text{Decrease in Price}}{\text{Original Price}} \right) \times 100\).
Substitute the values into the formula: \(\left( \frac{800 - 680}{800} \right) \times 100\).
Simplify the fraction and multiply by 100 to find the percent decrease.
