In order to clear out room for new merchandise, james decided to mark down some of the items for sale in his electronics store.

Jobisdone [24]

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%.

$\frac{64}{100} \times D = 41.60\\\\64D=41.60 \times 100\\\\64D=4160\\\\D=\frac{4160}{64}$

D = $65

Reduction: Dvd player = $65-41. 60=$ $23.40

<u>For </u><u>stereo tuners</u><u>:</u>

<u>Note:</u> You'll pay 78% since it was markdown by 22%.

$\frac{78}{100} \times S = 69.42\\\\78S=69.42 \times 100\\\\78S=6942\\\\S=\frac{6942}{78}$

D = $89

Reduction: Stereo tuner = $89-69. 42=$ $19.58

Now, we can calculate the difference in reduction of the cost price of both items:

$Difference = 23.4 -19.58$

Difference = $3.82

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