Question

The original price of a watch was $550. During a mid year sale, the selling price was $440. Find the percent discount

Answer 1

First, you would need to determine the discount amount.
$550 - $440 = $110

Next, you would need to create an equation for this problem. Let x represent the unknown percent discount.

`(110)/(550)` =
`(x)/(100)`

Cross multiply.
550x = 11,000

Now, all you would need to do is isolate the x. To do this, you would divide both sides of the equal sign by 550.
x = 20
x = 20%

The percent discount was 20%.

I hope this helps!
