This video is all about how to work out a reverse percentage and forms part of the playlist reverse percentages.
The question deals with Dave paying £5200 for a new car, after a 20% discount, and asks us to work out the normal price. The easiest way to deal with this is to change the percentage to a decimal and go from there.
I hope the video helps and please do leave a comment – thanks!
