So if I was to buy something that cost £15 and get 20% discount what would be the answer? cause i got an answer that equals to £3?

I did 15 x 0.20 = £3

What am I doing wrong?

@Misssaima786 no your right but the £3 is the 20% dicount you need to take the discount away from the origional so £15-£3=£12
