Question

The price of a computer was decreased by 7% to £500. What was the price before the decrease? Give your answer to the nearest penny.

Answer 1

£ 537.63

Explanation:

original price = 100%

selling price = 100% - 7% = 93% = £500

just do the proportion or ratio

`(100\%)/(93\%) = (original \: price)/(500)`

OP = 500 x 100% / 93%

OP = £ 537.634

rounded to the nearest penny and become £ 537.63
