Answer:
I'm not sure
Step-by-step explanation:
It looks as though there are 25 21-40 year-olds. 40% of 25 is 10, this is the amount that are AGAINST the increase. Therefore the ones in favor for the increase must be 25 - 10 = 15.
You should be able to follow the same process to get the 41-60 year-olds against an increase. Just be sure to read the given information carefully
First, you multiply 9 x 13 x 10 = 1170 which is the area of the whole triangle
Then, divide that, 1170, by 2 which equals 885.
So your answer (which im pretty sure is correct) 885
