y=66．答：两江校区各有36名、鲁能校区有66名学生准备参加演出．（3）∵鲁能校区有7人不能参加演出，∴鲁能校区有66﹣7＝59（人）参加演出．若两校联合购买服装，则需要70×（59+36）＝6650（元），此时比各自购买服装可以节约59×70+36×80﹣6650＝360（元），但如果两校联合购买100套服装，只需60×100＝6000（元），此时又比各自购买每套50元可节约59×70+36×80﹣6000＝1010（元），∴最省钱的购买服装方案是两校联合购买100套服装（即比实际人数多购5套）．20．解：（1）设建造A类桌游房间a间，则建造B类桌游房间（10﹣a）间，∵门店可供使用面积最多不超过165平方米，且要求该门店至少可同时容纳64名玩家游戏，∴15a+20(10―a)≤165 6a+10(10―a)≥64，解得7≤a≤9，∵a为整数，∴a＝7，8，9，∴有三种方案，方案一：建造A类桌游房间7间，建造B类桌游房间3间；方案二：建造A类桌游房间8间，建造B类桌游房间2间；方案三：建造A类桌游房间9间，建造B类桌游房间1间；（2）方案一的建造费用为：7×2+3×3＝14+9＝23（万元）；方案二的建造费用为：8×2+2×3＝16+6＝22（万元）；方案三的建造费用为：9×2+1×3＝18+3＝21（万元）；∵23＞22＞21，∴方案三最省钱，答：方案三：建造A类桌游房间9间，建造B类桌游房间1间最省钱．21．解：（1）设每盒A款的文具盒为x元，每盒B款的文具盒为y元，由题意得：3x+y=222x+3y=24，解得：x=6
