To find the unit price per T-shirt, divide the total cost by the number of T-shirts in the package.

Unit price per T-shirt ( = \frac{\text{Total cost}}{\text{Number of T-shirts}} )

Given that Michelle bought a package of three T-shirts for $18.75:

Unit price per T-shirt ( = \frac{18.75}{3} )

Unit price per T-shirt ( = $6.25 )
