Answer 1

amount has private access. You need to use getAmount().
Btw: you don't need an extra variable to return the value:

return getAmount() + getAmount() * 0.2;

return getAmount() + getAmount() * 0.05;

I first ran this by making the super class amount to public, but I know I am not supposed to change that to public. So I checked here and saw the getAmount method and that made more sense. The only thing is, is that I had to run the same code multiple time before it ran all correctly because I would get execution timed out as an output for some.
