Question

The price of a holiday was decreased by 12% to £600. What was the price before

the decrease? Give your answer to the nearest penny.

Answer 1

Explanation:

Price before decrease = £ x

If price before decrease is 100, then price after decrease = 100- 12 = £ 88

100:88 = x:600

`(100)/(88)=(x)/(600)\\\\(100)/(88)*600=x\\681.82=x`

Price before decrease = £ 681.82
