I have a maths test tomorrow and I'm not sure on how to answer questions like these:

"a pair of jeans is bought for £30, but in a sale a week later, 30% is reduced. What is the sale price?"

i feel like its a really easy question but my teacher isn't the best teacher, so if anyone could tell me the steps to do it itd be appreciated sm

Answer:

$21

Explanation:

30% = .3

multiply 30 by .3 and this equals 9 so you just subtract 9 from 30 because that is how much it went down from the sale. when you subtract 9 from 30 you get 21
