The actual pressure before the percentage increase is 36.5

<h3>How to calculate the Actual pressure?</h3><h3 />

New pressure = £39.42
Percentage increase = 8%

let

x = actual pressure

39.42 = x + (8% of x)

39.42 = x + (0.08x)

39.42 = 1.08x

x = 39.42 ÷ 1.08

x = 36.5

Therefore, the actual pressure before the percentage increase is 36.5
