A store owner purchases 40 shirts for $600. She then adds 40% to her cost and then tags each shirt with the new selling price. How much profit does she earn on each shirt?

40 shirts for $600 ... $15 each

40% markup ... .40 * 15 = 6

new selling price ... 15 + 6 = $21 ... $6 profit

To find out how much profit the store owner earns on each shirt, we need to calculate the selling price and subtract the initial cost per shirt.

Step 1: Calculate the cost per shirt.
The store owner purchased 40 shirts for $600, so the cost per shirt is $600 divided by 40, which equals $15.

Step 2: Calculate the selling price per shirt.
The store owner adds 40% to her cost. To find the amount added, we multiply the cost per shirt by 40%: $15 x 0.40 = $6.

To get the selling price per shirt, we add the amount added to the cost per shirt: $15 + $6 = $21.

Step 3: Calculate the profit per shirt.
To find the profit per shirt, we subtract the initial cost per shirt from the selling price per shirt: $21 - $15 = $6.

Therefore, the store owner earns a profit of $6 on each shirt.

To find out the profit earned on each shirt, we first need to determine the selling price of each shirt.

The store owner adds 40% to her cost, which means the selling price will be 100% (cost) + 40% (markup) = 140% of the cost.

To calculate the selling price of each shirt, we'll use the formula: Selling Price = Cost + Markup

The cost of 40 shirts is $600, so we divide the total cost by the number of shirts to find the cost per shirt:
Cost per shirt = Total Cost / Number of shirts = $600 / 40 = $15

Next, we calculate the markup amount:
Markup = Cost per shirt * Markup percentage = $15 * 40% = $6

Finally, we calculate the selling price per shirt:
Selling Price per shirt = Cost per shirt + Markup = $15 + $6 = $21

Now, to determine the profit earned on each shirt, we subtract the cost per shirt from the selling price per shirt:
Profit per shirt = Selling Price per shirt - Cost per shirt = $21 - $15 = $6

Therefore, the store owner earns a profit of $6 on each shirt sold.
