The amount of milk she got in the morning to make cheese is; 11.2 quarts
<h3>Understanding Fraction word problems</h3>
Let the amount of milk that she collected from her goats in the morning be x quarts
She used 25%. Thus, amount used = 25% * x = x/4 quarts
She now has 8.4 quarts left.
Thus, we can have the expression;
x - (x/4) = 8.4
3x/4 = 8.4
x = (4 * 8.4)/3
x = 11.2 quarts
In conclusion, amount of milk she got in the morning to make cheese = 11.2 quarts

The 1st row has 15 chairs.
The 2nd row has 15 + 3 = 18 chairs.
The 3rd row has 18 + 3 = 15 + 2•3 = 21 chairs.
The 4th row has 21 + 3 = 15 + 3•3 = 24 chairs.
The pattern continues, so that the n-th row has 15 + (n - 1)•3 = 3n + 12 chairs.
If there are 15 rows, then the total number of chairs is

The dvd player’s price was reduced by $3. 82 more than the stereo tuner’s price.
- Let the cost price of dvd players be D.
- Let the cost price of stereo tuners be S.
<u>Given the following data:</u>
- Markdown for dvd player = 36%
- Markdown for stereo tuner = 22%
- Markdown cost for dvd player = $41.60
- Markdown cost for stereo tuner = $69.42
To determine which item’s price was reduced by more, and by how many dollars:
First of all, we would calculate the cost price of each item.
<u>For </u><u>dvd players</u><u>:</u>
<u>Note:</u> You'll pay 64% since it was markdown by 36%.

D = $65
Reduction: Dvd player =
$23.40
<u>For </u><u>stereo tuners</u><u>:</u>
<u>Note:</u> You'll pay 78% since it was markdown by 22%.

D = $89
Reduction: Stereo tuner =
$19.58
Now, we can calculate the difference in reduction of the cost price of both items:

Difference = $3.82
Therefore, the price of the dvd players was reduced by $3. 82 more than the price of the stereo tuners.
