The correct answer is A, as the DVD player's price was reduced by $ 3.82 more than the stereo tuner's price.
In order to clear out room for new merchandise, James decided to mark down some of the items for sale in his electronics store, and he marked down DVD players by 36%, and he marked down stereo tuners by 22%, if DVD Players cost $ 41.60 after the markdown and stereo tuners cost $ 69.42 after the markdown.
To determine which item's price was reduced by more, and by how many dollars more was it reduced, the following calculation must be performed:
- 100 - 36 = 64
- 64 = 41.60
- 100 = X
- 100 x 41.60 / 64 = X
- 4160/64 = X
- 65 = X
- 65 - 41.60 = 23.40
- 100 - 22 = 78
- 78 = 69.42
- 100 = X
- 69.42 x 100/78 = X
- 6942/78 = X
- 89 = X
- 89 - 69.42 = 19.58
Therefore, the DVD player's price was reduced by $ 3.82 more than the stereo tuner's price.

Answer:
L = 2r + 3
Step-by-step explanation:
Given parameters:
Area of rectangle = 14r + 21
Width of the rectangle = 7ft
Unknown:
Length of the rectangle = ?
Solution:
If the length of the rectangle is designated as L;
Area of a rectangle = Length x width
Now insert the parameters:
14r + 21 = L x 7
L = 
L = 2r + 3
