The original price of the car before the decrease was £ 900

Depreciation formula

Depreciation = Original amount – percentage of depreciation

How to determine the original amount

Let the original amount be T

  • Depreciation = £ 720
  • Percentage = 20%
  • Original amount (T) =?

Depreciation = Original amount – percentage of depreciation

720 = T – (20% of T)

720 = T – 20T/100

Multiply through by 100

720 × 100 = 100T – 30T

72000 = 80T

Divide both side by 80

T = 72000 / 80

T = £ 900
