Lets day the original price of the dvd player was $100,
36% marked down means you pay $64x
64x = $41.60
100x = 100/54 x 41.60 = 4160/64 = #65.00 = original cost
similarly, stereo tuners = 100/78 x 69.42 = 6942/78 = $89 original cost
DVD = 65- 41.60 = $ 23. 40 less
Stereo = 89- 69.42 = $ 19.58 less
Diffrence is $ 3.82
so your answer is the dvd player price was reduced by $3.82 more than the stereo tuner.

a)
b)
Since we can't divide by zero, we need to find when:
But before, we can factor the numerator and the denominator:
Now, we can conclude that the vertical asymptotes are located at:
so, for x = -3:
For x = 4:
The tax is $2.80 but the total is $42.80
