I am trying to do is(people * ticket price)-((number of shows * 20)+(people *

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    ...

(total_profit p s)    (* p 5( - (* p 0.5(+ s 20)))))

Took a little bit of tooling but got the brackets right

(define (patrons p)
;p 	a number
...
)

(define (shows s)
;s	a number
...
)

(define (total_profit p s)
(- (* p 5)
(+ (* s 20)(* p 0.5))))

```
