问题: A boy was offered a bouns if he sold 100 subscriptions to a magazine. Each day he sold subscriptions
A boy was offered a bouns if he sold 100 subscriptions to a magazine. Each day he sold subscriptions more than he had sold on the previous day,and on the eighth day he reached a hotal of exactly 100 subscriptions. How many subscriptions did he sell on the first day?
He sold ( )subscriptions on the first day.
解答:
原题有个小错误，bouns应为bonus，hotal应为total
句子的意思是：
如果可以卖出100份某杂志，男孩就会得到提成（或译资金）。男孩每天都比前一天都买三份杂志，在第八天的时候，他刚好卖出100份的杂志。请问，男孩第一天卖出多少分杂志？
他第一天卖出了___2分____份杂志。
这八天的情况是：2+5+8+11+14+17+20+23=100
