Duru has an ice-cream stand, which she opens on warm days. When open for business, her daily profit, PPP, is a function of the number, nnn, of cones she sells and can be modeled by the function P(n)=2n-20P(n)=2n−20P, left parenthesis, n, right parenthesis, equals, 2, n, minus, 20. Additionally, she finds that the number, CCC, of cones she sells is a function of the average temperature, ttt, in degrees Celsius (^\circ\text{C})(∘C)left parenthesis, degrees, start text, C, end text, right parenthesis, and can be modeled by the function C(t)=50+10(t-10)C(t)=50+10(t−10)C, left parenthesis, t, right parenthesis, equals, 50, plus, 10, left parenthesis, t, minus, 10, right parenthesis. Which expression gives Duru's profit on a day with an average temperature of t^\circ\text{C}t∘Ct, degrees, start text, C, end text?
