Explanation:
The markup on each shirt is equal to $3.00 * 150% = $4.50, since a markup of 150% means adding an amount equal to 150/100 = 1.5 times the original price.
The selling price for each shirt is equal to the original price of $3.00 plus the markup of $4.50, which is a total of $3.00 + $4.50 = $<<3+4.5=7.50>>7.50.
Therefore, the selling price for each shirt is $7.50.
