In a sale, normal prices are reduced by 12%

The sale price of a digital camera is £132.88

If something is reduced by 12%, it must only be worth 88% of what it once was.

So, let P be the original price.

And we have...

88% of P  = 132.88      ....or, mathematically.......

.88 * P = 132.88           divide both sides by .88

P = £ 151

multiply 12x132.88 divide it 100 = 15.94

then just add 132.88 + 15.94 = 148.82 (original price)
