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:not sure
Step-by-step explanation:
Sorry
Answer:
i think its personally B
Step-by-step explanation:
first you need to find the slope of he current equation by changing it to y=mx+b
3x-2y=9 subtract 3x from both sides
-2y=-3x+9 divide both sides by -2
y+3/2x-9/2 Your slope of the existing is 3/2 or 1 1/2
a perpendicular line has the opposite reciprocal slope so 3/2 would be -2/3
-3 is your y intercept. now you can make your equation
y=-2/3x-3
