DOUBLE JEOPARDY!!!!!!! :) Write an inequality for this question: The math club will sell rolls of wrapping paper and ribbon as a fundraiser. They can order up to 300 items as long as they spend less than $600. They also must buy at least as many rolls of as many rolls of wrapping paper as rolls of ribbon. Each roll of wrapping paper costs the club $2. Each roll of ribbon costs the club $3.
