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:
Step-by-step explanation:
your welcome
Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know:
</span>
<span>The new ratio is obtained like this:
</span>
.
From the above equation we get
.
then
Solving the above equation for y we get:
So
So the first tree is (400-160=240) more taller than cherry tree.
