From the question, we are asked to use the original price and the markdown or the markup to find the retail price.
So given the following:
Original price: $125
Markdown: 30%
We are asked to find the reatil price.
To get the retail price, you first get 30% of $125 and then subtract what you have from the original price.
So,
30% 0f $125
= 30/100 * 125
= 0.3 * 125
= $37.5
Therefore, the retail price is:
= $125 - $37.5
= $87.50
Therefore, the retail price is $87.50
