What I am having trouble navigating is the brackets. Simply in normal math what I am trying to do is (people * ticket price)-((number of shows * 20)+(people * cost per person)) Contrcat : total profit : attendees performance -> number ;; Purpose to calculate total profit of a theatre per show ;;Example: (total profit 20 1) should produce $70 ;;Defintion: ( define (- profit cost)) (* patrons 5( - (* patrons 0.5(+ (* shows 20))))) (define (patrons p) ;p a number ... ) (define (shows s) ;s a number ... ) (define (total_profit p s) (* p 5( - (* p 0.5(+ s 20)))))
