[racket] Order of Operations - Getting the brackets.

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)))))
