Answer:

We have that y = 21 when x = 11.

Step-by-step explanation:

We solve this question by proportions, using a rule of three.

Since they vary inversely, we apply the inverse rule of three, that is, with lateral multiplication instead of diagonal.

33 - 7

y - 11

So

11y = 33 -7

y - 11

Dividing both sides by 11

Y = 3 * 7 = 21

We have that y = 21 when x = 11.

Step-by-step explanation:

Here is the complete question: You are making juice from concentrate. The directions on the packaging say to mix  1 can of juice with 3 cans of water to make orange juice. How many 12 fluid ounces cans of the concentrate are required to prepare 200 6-ounce servings of orange juice?

∴ 200\times 6= 1200\ ounce

Let there be x ounce of concentrate and 3x ounce of water to make 1200 ounce of orange juice.

Now, x+3x= 1200

∴ x= 300 ounce

Next, lets find out how many cans of 12 ounce is required.

\frac{300}{12} = 25\ cans
