Maria sold bumper stickers to raise money for a public library. 

She paid $2.25​ to make each bumper sticker and then sold each bumper sticker at a marked-up price to make a profit. 

She sold all $80​ bumper stickers that she had made. 

She made a total profit of $400​ .

What is the approximate percent Maria marked up the cost of each bumper sticker to make her total profit?

To find the markup percentage, we first need to calculate the total cost, total revenue, and total profit.

Total cost = $2.25 per bumper sticker x 80 stickers = $180
Total revenue = $400 + $180 (total cost) = $580
Total profit = $400

Now, we can calculate the markup percentage:
Markup = Total revenue - Total cost = $580 - $180 = $400
Markup percentage = (Markup / Total cost) x 100
Markup percentage = (400 / 180) x 100
Markup percentage ≈ 222.22%

Maria marked up the cost of each bumper sticker by approximately 222.22% to make her total profit.
