Bonjour! J'ai un probleme de mathematiques en anglais a résoudre. Est ce que quelqu'un pourrait m'aider?

Le probleme est le suivant:
Wheel Garden centre has a policy that price increases will never be more than 6%.
This month, the plastic sheet costs only £3.75.
Next month they will Increase the price of plastic sheet to £3.99 per roll.
Is this increase in line with their policy? Explain.

Merci d'avance

the increase is  of

(3.99- 3.75)  / 3.75  =  0,24  / 3,75 = 0,064  = 6,4%

they have increased more than 6%; they don't follow their policy
