The price of a phone decreases by 20%
This 20% decrease reduces the price of the phone by £150.
Work out the price of the phone before the decrease.

Respuesta :

£750

===============

Let the initial price be x.

20% of the price is 0.2x and it is equal to £150.

Set up equation and solve for x:

  • 0.2x = 150
  • x = 150/0.2
  • x = 750

So, the price of the phone before the decrease was £750.
