Answer:
c
Step-by-step explanation:
Since the ratio is 3:4, and 12/4 is 3 than you do 3x3 and get 9 so the answer is 9:12 or 9 boys and 12 girls. To check your answer, you can do 3/4 (for 3:4) and that is 0.75. If you do that with 9:12 you also get 0.75.
It is 39
Because you have to count the little dots all the way till it is around the most age.
$24.50*0.3 = $7.35
The answer is $7.35
