**Solution:**
We are given that in order to make orange juice, 1 can of concentrate is used and 3 cans of water. Thus, we can set up the following ratio:

Concentrate: water = x : 3x

We need to determine how many cans of concentrate are needed to prepare 200 6-ounce servings of orange juice, or 200 x 6 = 1,200 ounces.

We can create the following equation to determine the number of ounces of concentrate needed:

x + 3x = 1,200

4x = 1,200

x = 300 ounces

Since there are 12 ounces per can, 300/12 = 25 cans are needed to make 1,200 ounces of orange juice.

**Alternate Solution:**
According to the instructions, one 12 oz can will be mixed with 3 x 12 = 36 oz of water. Thus, each 12 oz can yields 12 + 36 = 48 oz of orange juice. To make 200 x 6 = 1,200 oz of orange juice, we need 1,200/48 = 25 cans.

**Answer: A**
