Each park individual ticket is 5 yuan, each group ticket is 30 yuan, for no more than 10 people to enter the park. Buy 10 or more group tickets and get a 10% discount. For an autumn outing in a certain unit, the money originally prepared was just enough for tickets for 145 people, and two people were added temporarily. Fortunately, both of them brought the same amount of money, so that 147 people just happened to be able to buy tickets to enter the park. How much did the two bring together?
公园个人票每张5元，团体票每张30元，供不超过10人入园．买10张以上的团体票，可优惠10%．某单位秋游，原来准备的钱刚好够145人的门票用，临时又加了两个人，幸好两人每人都带了相同多的钱，这样147人刚好都能购票入园．这两人共带了多少元．
