11. The negative 8 had to go to the positive 3. You add 8 automatically to get yourself to 0. Once you do that you add three to make them the same to find the distance. The answer is 11.
$2.49 -------------------100 %
$1.99 ------------------- x %
-------------------------------------
2.49 : 1.99 = 100 : x
x = ( 1.99 * 100 ) / 2.49 = 79.9 %
100 % - 79.9 % = 21.1 % ( Decrease )
$1.99 -------------------- 100 %
$2.49 -------------------- x %
------------------------------------
1.99 : 2.49 = 100 : x
x = ( 2.49 * 100 ) / 1.99 = 125.1 %
125.1 % - 100 % = 25.1 % ( Increase )
The percents of change are not the same.
The greater change is during the increase of price ( 25.1 % > 21.1 % ).

<h3>5 gallons of 50 % alcohol solution is used</h3>
<em><u>Solution:</u></em>
Let "x" is the gallons of 50 % alcohol solution
Then, 10 gallons is 35 % solution
The, 10 + x is the gallons of 40 % solution
Then, according to question,
"x" gallons of 50 % solution is mixed with 10 gallons of 35 % solution to get 10 + x gallons of 40 % solution
Therefore,
Thus 5 gallons of 50 % alcohol solution is used
