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.
