标题: 谁能把price list四舍五入的那道jj题逐字逐句的翻译一下

The estimated amount in the price list rounded to 1$. How much is the sum of the estimated amounts within 6$ of the sum of the actual amounts in the list. (1)There are fewer than 11 amounts in the list. (2)Each estimated amounts is 5$

rounded to 1$ 是啥意思

How much is the sum of the estimated amounts within 6$ of the sum of the actual amounts in the list：能否帮忙分析一下语法：到底再问什么？within6$做什么成分？

有人选E，有人选A,之所以不同看上去是因为对how much is...这句的理解不同。期待ing.....

rounded to 1$ 是四舍五入到美金的个位.

how much 也不大了解,期待中>>.....

看到一个牛人的jj翻译了这个题目，大概是这个意思：一个人买东西，列了个list,list上的价格都四舍五入到$1，问list 是否至少有6件东西。

我觉得选e把

JJ汇总里面摘的

424. DS 买东西把价格Round to nearest integer 问估计价和实际价偏差
在6内？
一共买的东西Less than 11
每个东西的价格All round to 5
Key: A

we need two premises, a) how many items we bought;b) difference between truth cost and calculated cost of each item

1)we bought <=11 items, round to nearest integer, the max difference is lim(0.4999999....)=0.5, 11*0.5=5.5<6, sufficient
2)still, the max difference is 0.5, but no information about how many items, not sufficient
