Brett wants to paint his master bedroom. The paint costs $21 per gallon and the primer costs $15 per gallon. He does not want to exceed $185 for the paint and primer. He has determined that he needs at least 5 gallons of paint and primer in total. If p represents the number of gallons of paint and r represents the number of gallons of primer, which system of inequalities represents Brett’s situation?
