At the beginning of each school year, Madison Middle School orders new shirts for the entire student body. Each student receives one shirt. Each shirt is the same price, s, and the school orders enough for n students. Which equation represents the proportional relationship between P, the total price of the shirts, and the number of students?

Question

A. s + n = p

B. n/s = p

C. sn = p

D. s/n = p

Answer 1

The total price of the shirts (P) can be calculated by multiplying the price of each shirt (s) by the number of students (n). This gives us the equation:

\( P = s \cdot n \)

So the equation that represents the proportional relationship between P, the total price of the shirts, and the number of students is:

C. \( sn = P \)
