Gillian can spend up to $300 buying both cotton shirts and wool shirts for her club. The cotton shirts cost $15 each and the wool shirts cost $20 each. The number of wool shirts Gillian will buy will be at least 3, and no more than half the number of cotton shirts she buys. The graph shows the feasible region, where x represents the number of cotton shirts and y represents the number of wool shirts. Which ordered pairs meet all the constraints and make sense in context of the situation?
