第一题：有一笔钱平均分给10个人,由于2人缺席,出席的每个人多得了30美元,求总钱数.
已知,总钱数为X,平均分给10个人可以每人可以得到X/10,平均分给8个人每人可以得到X/8
根据题意,列方程X/8-X/10=30,解得X=1200,所以总钱数为1200美元
第二题：72颗弹子被分成两份,少的那一份弹子数的7倍等于多的那一份弹子数的5倍,求少的那一份弹子数是多少.
已知,少的那一份弹子数为X,则多的那一份弹子数为7X/5
根据题意,列方程X+7X/5=72,解得X=30,所以少的那份弹子数为30

1.一笔钱本来有10个人分，现在有两人没来，结果剩下的八个人每人多拿30美元。求这笔钱的总额？------三八240，所以10个人的话每人能分得120美元。八个人就是150美元
