Hello,
I claim there is a typo in the online version of HtDP:
Exercise 4.3.3, the first condition should be
[(<=n1000) (*.040n)]
instead of
[(<=n1000) (*.0401000)]
Why?That's what's in the printed book too and it seems perfectly
reasonable to me.
Well, it's a "what is the value of this expression?" exercise, so
technically it could have been anything. However, to solve the intended
problem of bank interest, Jakub is right: it should be (* .040 n) in the
first case (otherwise people would earn the same $40 interest on a
deposit of a penny as on a deposit of $1000.)
Ah, right. I didn't read enough context to see that.
David
