Solutions to Equations and Inequalities

A store sells notepads in packages of 24 and packages of 6. The organizers of a conference need to prepare at least 200 notepads for the event. Would they have enough notepads if they bought these quantities? Seven packages of 24 and one package of 6. Five packages of 24 and fifteen packages of 6. Write an inequality to represent the relationship between the number of large and small packages of notepads and the number of notepads needed for the event.
