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.
