Alice has hired you to improve some code used at the restaurant. The code we’ll be improving on is shown below.
Read through the code line-by-line with your partner before writing down your observations in the tables below.
; cost :: String ‑> Number
; given a item, produce the cost of that item
(define (cost item)
(cond
[(string=? item "onion rings") 3.5]
[(string=? item "fried tofu") 5.25]
[(string=? item "pie") 2.25]
[else "Sorry, that’s not on the menu!"])
