Total billed amount of fridge including VAT = $480

Let us assume the price of the fridge before the VAT is added = $x.

20% of VAT is added.

20% of x is 0.20x.

Total amount = 480.

Let us set an equation to find the value of x.

<h3>x+0.20x = 480.</h3>

1.20x = 480.

Dividing both sides by 1.20, we get

1.20x/1.20 = 480/1.20

x= 400.

<h3>Therefore, $ 400 is the price of the fridge before the VAT added.</h3>
