A company sells sneakers and has a revenue that can be represented by the function R(s) = 90s – s2, where s represents the number of pairs of sneakers sold. The sneaker company has a fixed cost of $1,500, and each pair of sneakers costs $30 to manufacture. Which of the following functions represents the profit P(s) of the sneaker company?

P(s) = – s2 + 120s + 1,500
P(s) = – s2 + 60s + 1,500
P(s) = – s2 + 120s – 1,500
P(s) = – s2 + 60s – 1,500
