Jenna bought tee shirts for $4.50 each. She is selling then for $6 each. What was the percent of the mark up?

Answers

Price at which Jenna bought a single tee shirt = $4.50
Selling price of each tee shirt $6
Then
Profit on each tee shirt made by Jenna = (6 - 4.50) dollars
   = 1.50 dollars
Percentage of profit made by Jenna on each shirt = (1.5/4.5) * 100 percent
   = 150/4.5 percent
      = 33.33 percent.
The percentage on the mark up price for Jenna was 33.33%.I hope I have helped you andthe procedure for doing such problems is clear to you.
