A smartphone originally costs $800 but is now sold for $ 680 \$680 . Determine the percent decrease in price.

So smartphone originally cost $800 but is now being sold for $680 Determine the percent decrease in price. Now remember to find percent change, we need to find the difference between our two values and then divide by the original value. So first, let's identify our new price and our original price. Our original price was $800 and then it changed to $680 So in order to find our change in price, we need to do new minus original. So six eighty minuteus 800 is negative 120. And then to find our percent change, we need to divide that amount by our original cost. So negative 120 divided by 800, which equals 0.15. And don't forget, it's negative. Converting this to a percent, we get negative 15%. So we can say that there was a percent change of negative 15%. But this question is asking for the percent decrease. So we could also word this and say we saw a percent decrease of 15%. When we word it this way, remember we can drop that negative because the word decrease implies that the percent is negative. So this here would be our final answer.

A smartphone originally costs $800 but is now sold for $ 680 \$680 . Determine the percent decrease in price.
