The Royal Fruit Company produces two types of fruit drinks. The first type is 55% pure fruit juice, and the second type is 80% p
seropon [69]

We need 56 pints of the 55 % <em>pure fruit</em> juice and 84 pints of the 80 % <em>pure fruit</em> juice to prepare 140 pints of 70 % <em>pure fruit</em> juice.

<h3>How to use weighted averages to find the correct juice concentration</h3>

In this problem we have to use two kinds of juice with different concentrations. To get a certain concentration, we must adjust quantities of each kind and <em>weighted</em> averages offers a method that is easy to apply:

70 · 140 = 55 · x + 80 · (140 - x)

70 · 140 = 80 · 140 - 25 · x

25 · x = 10 · 140

x = 56

We need 56 pints of the 55 % <em>pure fruit</em> juice and 84 pints of the 80 % <em>pure fruit</em> juice to prepare 140 pints of 70 % <em>pure fruit</em> juice.

Which of the following options have the same value as 80% of 22?
Alex_Xolod [135]
80% of 22 can be written in the following ways:

1) 80% of 22 = 17.6

2)
0.8 x 22 = 17.6
The percentage is converted into decimal form.

3) 80/100 x 22 = 17.6
The percentage is converted into fraction form.

80/100 can be simplified to 4/5, and the point 3 can also be written as:

4) 4/5 x 22 = 17.6

Thus, following options have the same value as 80% of 22.
Option <span>A. 80/100 ⋅ 22
Option </span><span>D. 0.8 ⋅ 22
Option E. 4/5 ⋅ 22</span>
