Each camper gets a 1/2 cup of juice. For each mux how much concentrate and how much water are needed to make juice for 240 campers.
Mix A
2 cups concentrate
3 cups water
Mix B
5 cups concentrate
9 cups water
Mix C
1 cup concentrate
2 cups water
Mix D
3 cups concentrate
5 cups water

1/2 of 240 = 120 cups
A. 120 / 5 = 24
24 * 2 = 48 cups concentrate
24 * 3 = 72 cups water
I'm sure you can use that example to figure the other problems out.
Please post your answers and we'll be glad to check them. 
B=70 cups concentarte:126 cups water
C=40 cups concentarte:80 cups water
D=90 cups concentrate:150 cups water 
B = 70 + 126 = 196 cups  OOps  too much
C = Correct
D = 240 cups  Oops  you've just made twice as much as you need. 
B= I can not seem to figure this particular question correctly, when I get an answer it doent add up or doenst make sense.
D=45 cups concentrate: 75 cups water
