Answer:

For this case we know that september for any year have 30 days and that represent the 100% for the total of days on this month.

We know the condition that 40% of the days in September were sunny and we are interested in find the X number of days sunny, so we can apply this proportion rule

[tex]\frac{X}{40}= \frac{30}{100}[/tex]

And solving for the value of X we got:

[tex] X = \frac{30}{100}*40 = 12[/tex]

So then we can conclude that about 12 days in September were sunny for this case
