Answer:

The selling price will be $52 dollars.

Step-by-step explanation:

If the skates have 30% markup we need to ADD up this percentage to the original selling price.

First we will use a rule of three to find the 30% of 40.

$40 -- 100%

x    -- 30%

[tex]x=(40)(30)/100\\x=12[/tex]

Now we add up the $12 to the $40 skates.

The selling price would be 40 +12 = 52 dollars.
