bills, the bellboy pocketed 2 of those dollars and gave each of the men $1.
00 back. This means the men each paid $9.00 for the room. So 3 x 9 = 27 then
one adds the 2 the bellboy pocketed and that makes $29.00. What happened
to the 30ith dollar? |

发帖数: 22772 | 3 这笔交易总量是２７块，房假２５块加小费两块。
３个客人可以每人付１０块拿回一块找零，也可以每人付２０块拿回１１块找零，这都
等价于每人付９块 |

wrong
should be
"This means the men each paid $9.00 for the room and the boy."
then
3*9=27=30-3*1
按照题目算法boy 拿得钱算了两次

27和2不应该加在一起。房客掏了27刀，房东和小二各入25和2，27+2毫无意义
换一种问法，如果小二只给每个房客一个quarter，算起来小二还创造了不少财富呢
