please help with this question.

Answer:
27.27%
Step-by-step explanation:
Given that,
Initial price = 11
Final price = 8
We need to find the percentage change in the price. It can be calculated as follows :
% = [(final-initial)/initial] × 100
So,
[tex]\%=\dfrac{11-8}{11}\times 100\\\\\%=27.27\%[/tex]
So, the percentage decrease is 27.27%.
