Hello i need ur help please?

£67.87

Step-by-step explanation:

(Total increase) = (Original Amount) × (Multiplier)²

Rearrange the equation to find the original amount

(Total increase) ÷ ( Multiplier)² = (Original amount)

To find the Multiplier, add 1 to 3% = 1.03

Substitute what you can

(72) ÷ (1.03)² = Original amount

£67.8669054576 = Original Amount

Round up the number to 2 decimal places since it is British Pounds currency

£67.87 = Original Amount
