C. P = sn

explain

The equation P = sn represents the proportional relationship between the total price of the shirts (P) and the number of students (n). This equation states that the total price is equal to the product of the price per shirt (s) and the number of students. This makes sense because if the number of students doubles, then the total price should also double, as each student still receives one shirt.
