So they want to know how many cans of concentrate it takes to make 1200 ounces of juice

So from the ratio, we know that 1 in 4 cans in the total mix is concentrate.

So we need to isolate how much concentrate is within the juice. Lets divide 1200oz/4oz = 300 oz of concentrate within the juice.

300/12oz per can of concentrate = 25 12oz cans of concentrate

Answer is A

I converted concentrate to gin and juice to tonic to make it easier mentally, the lime is isolated

conc : water = 1:3

say 'n' is the number of cans
we have:
12(n) oz of conc. and 36n oz of water and get 200(6) oz of juice

(36n oz of water becos we mix 3 times conc)

ie
12n+ 36n = 200*6
solving for n we get 25
