The above is just a helper function (like > "pay"); it's not the function you tell the users about.

I have re-writeen this one too many times I have lost focus. This is where I was embedding a function again. (define (gross hours) (* 12 hours )) (define (pay (gross hours)) (cond [(>= gross 480) (+(*(- gross 480)0.28)36)] [(>= gross 240) (*(- gross 240)0.15)] [(< gross 240) 0]))
