Final answer:
To calculate the markup, multiply the cost of the dress shirts by 0.35. The selling price of each dress shirt would be 1.35s dollars.
Step-by-step explanation:
To calculate the markup, we need to multiply the cost of the dress shirts by the markup percentage. Since the markup is 35%, we multiply the cost of the dress shirts by 0.35.
Let's say the cost of each dress shirt is s dollars. The markup on each dress shirt would be 0.35s dollars. So, the selling price of each dress shirt would be s + 0.35s = 1.35s dollars.
