to work this out, you can use something that my math teacher calls multiplier method. BAsiclly, say you wanted to add 25% onto 269.99, you would times by 1.25, as this would mean you wuld have the loriginal alue, plus one quarter, 25%.

So to take 25%off, you would times it by 0.75.

269.99x0.75= 202.4925
