Hi,(adsbygoogle = window.adsbygoogle || []).push({});

This is one of the question from my hw, i don't even understand what it's asking? Please shed some light on it.. thx

what is the smallest value of k such that any integer postage greater than k cents can be formed by using only 4-cent and 9-cent stamps? Show that k cents in postage cannot be formed and use induction to prove that all larger values can be formed.

thank you!
