Last Sunday I went to The Summer Palace with my friends. When we got off the bus, we couldn't find our way. So we asked a man nearby. He was kind and friendly. He told us how to get to the Summer Palace. We thanked him for his help. With his help, we found the place easily. We all have troubles sometimes. If we can, we should try our best to help others. If everyone give somebody a hand, the world will be more beautiful.

19+1=20（天）
30x+12X（20+x）=510
30x+ 12X20—12x =510
30x+240+12x =510
18x+240+240 = 510—240
18x÷18 =270÷18
x =15（天）

存入5000元记作+5000元，取出3000元，记作-3000元；
故答案为：+5000，-3000．

因为用先进先出法,也就是先进来的货物（就是先前的存货）50个,总价是50000.因为需要100个,再从后来购进的100个中取50个,每个成本是1050,总价是502500,最后这100个的总价就是50000+502500=102500
