The chart below shows the population distribution for the 2,400 occupants of the city of Centre Hill.
Adult Male Adult Female Child
% Living in Uptown 9 8 6
% Living in Midtown 22 20 15
% Living in Downtown 21 22 12
% Living in Suburbs 48 50 67
If there are an equal number of adults and children, and adult females outnumber adult males by 200, what is the sum of the women living uptown and the children living in the suburbs of Centre Hill?
Here's how I did it: There are 1200 adults and 1200 children, since it says that there's an equal amount
Females outnumber males by 200, so there are 800 females and 400 males
8% of 800 is 64
67% of 1200 is 804
64 + 804 = 868
Is this correct? I'm just wondering because the answer key says that it's 860, so I wanna know if it's a typo or if I went wrong somewhere. Thanks for the help!
"Females outnumber males by 200, so there are 800 females and 400 males"
... does that look correct?
maybe 700 and 500?
