Basically, the question is asking, what will happen if we increase 9 by 30%?

first, what is 30% of 9?
$\frac{30}{100}*9= \frac{3*9}{10} =2.7$

So, the increase will be by 2.7 days,

So the total amount will be 9+2.7=11.7 - this is the correct answer.

Hope your day is going well

Once two people answer your question there at the top of the question that they answer should have a crown and the words mark the Brainliest. Then it will go yellow when you mark it and it will also give you points
