Schmidt Industries makes four different snake traps; the Harlan, the Gaylen, the Leah and the Matthew. The Harlan sells for $$200$ and has $$80$ in parts; the Gaylen sells for $$150$ and requires $$60$ in parts; the Leah sells for $$100$ and has $$40$ in parts; and the Matthew sells for $$75$ but requires $$20$ of parts.
