Question

cameras actual price was $ 400. after discount its price was $280. calculate the percentage reduction in the price of the camera.

Answer 1

30% discount

Explanation:

Let the percent reduction be x%

Actual price =$400

Discounted price=$280

Therefore, by the problem =>
`400-x%400=280`%*400=280

=>
`400-(x)/(100) *400=280\\400-4x=280\\-4x=280-400\\-4x=-120\\4x=120\\x=120/40\\x=30`

There was 30% discount on the camera
