I might be able to help but a picture of the problem or the equation might work too
Answer:
A "sample" from a population is a small group of poeple chosen, such as 200 people is a sample of people chosen from a total of 5000
The correct answer is two or four
So 3 apples=6 dollars
therefor if we divide both sides by 3
1 apple=2 dollares
so therfor for every 1 apple, you pay 2 dollars
so if 12 apples
12 times 2=24
24 dollars
anonther way is
3 apples=6 dollars
6 apples=12 dollars
9 apples= 18 dollars
12 apples= 24 dollars
The correct answer to this question would be list C.
