The price of a necklace was increased by 20% to £144. what was the price before the increase.

£120

Step-by-step explanation:

If the price was increased by 20% to £144, that means that 120% of the original price is £144. Therefore, I set up the following equation:

1.2x=144

So, just divide both sides by 1.2 to get:

x=120.
