In a half price sale, all original prices are halved or divided by 2.

Example 1

How much will a CD costing £10.50 cost in this half price sale?

Answer

We must work out £10.50 ÷ 2 = £5.25

Example 2

How much did a CD cost originally, if it is priced at £10.50 in this half price sale?

Answer

We must work out £10.50 x 2 = £21.00
