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.
x+0.20x = 480.
1.20x = 480.
Dividing both sides by 1.20, we get
1.20x/1.20 = 480/1.20
x= 400.
Therefore, $ 400 is the price of the fridge before the VAT added.
