To find the percent markup Maria applied to each bumper sticker, we first need to calculate the total cost of making all 80 bumper stickers. Since she paid $2.25 to make each bumper sticker and she made 80, the total cost would be 2.25 * 80 = $180.

Next, we need to find the total revenue she generated from selling all 80 bumper stickers. Since she made a profit of $400 and sold all 80 bumper stickers, the total revenue would be the total cost + profit = $180 + $400 = $580.

Now, we can calculate the price at which she sold each bumper sticker. $580 (total revenue) / 80 (number of bumper stickers) = $7.25.

To find the percent markup, we need to calculate the difference between the selling price and the cost, and then divide that by the cost. Markup = ($7.25 - $2.25) / $2.25 * 100% = 222.22%

Therefore, Maria marked up the cost of each bumper sticker by approximately 222.22% to make her total profit of $400.
