return cost -= 50 is not possible,
-= is a shorthand, without shorthand we get:
return cost = cost - 50
so you try to(re-)assign a variable and returning, that is too much operations in a single line
Does it mean I shall change “return cost -=50” to “cost = cost -50”?
I tried that. It doesn’ work.
that is a possibility. Then you will need to
return cost later.
