The discussion focuses on proving that any amount \( n \ge 32 \) can be expressed as \( 5x + 9y \) where \( x \) and \( y \) are non-negative integers. An initial case is provided with \( n = 32 \) showing \( x = 1 \) and \( y = 3 \) as a valid solution. The proof employs mathematical induction, assuming the statement holds for some integer \( k \ge 32 \) and demonstrating it for \( k + 1 \). The discussion also explores specific cases for \( k + 1 \) based on the values of \( y \), leading to valid constructions for \( n \). The conclusion affirms that all integers \( n \) from 32 onward can indeed be represented in this form.
