A ) The Original price of music player before it was marked down by is $512
B ) The price that store paid for player is $256
C ) The difference between discount price and price paid by store is $128
Step-by-step explanation:

A ) The sale price of music player = $128
The music player is marked down by of original price
Let The original price = $x
Now, According to question
of original price = $128
i.e × $x = $128
Or, x = 128 × 4
∴ x = $512
So, The Original price of music player before it was marked down by is $512
B ) The music player is marked up by before it was placed on sales floor .
Let The price that store paid for player = $y
Now, According to question
∵ The original price of player = $512
So, The price that store paid for player = × original price of player
i.e y = × $512
Or , y = $256
So,The price that store paid for player = $256
C ) Let The difference between discount price and price paid by store = $z
So, According to question
z = y - discount price
Or , z = $256 - $128
∴ z = $128
So, The difference = $128
Hence, A ) The Original price of music player before it was marked down by is $512
B ) The price that store paid for player is $256
C ) The difference between discount price and price paid by store is $128
