Question 1209545
<br>
The ratio of females to males was 7 to 5<br>
7x = # of females
5x = # of males<br>
There were twice as many women as girls<br>
To avoid working with fractions, revise our expressions for the numbers of females and males:
21x = # of females
15x = # of men<br>
Again, there were twice as many women as girls:<br>
14x = # of women
7x = # of girls<br>
There were twice as many boys as men<br>
10x = # of boys
5x = # of men<br>
There were 68 more girls than men:<br>
7x = 5x+68
2x = 68
x = 34<br>
# of men: 5x = 170
# of women: 14x= 476
# of boys: 10x = 340
# of girls: 7x = 238<br>
Total number of people: 36x = 1224<br>
ANSWER: 1224<br>
