According to the direction on a can of frozen orange juice concentrate, 1 can of concentrate is to be mixed with 3 cans of water to make orange juice. How many 12-ounce cans of the concentrate are required to prepare 200 6-ounce servings of orange juice?
I must be having brain freeze...could you explain 12n + 12*3*n ?
12n + 12*3*n = Total Quantity of Juice
12n = Conccentrate
12*3*n = Water (1 can of concentrate is to be mixed with 3 cans of water, so for "n" can of water its 3*n, Also the each can contail 12 oz.
So this 12n + 12*3*n adds up the total quantity.
