5辆同样的汽车共运货
1.4×12×5＝84吨

华联更便宜,1、6,另一个1.8

一共是40人,需要40瓶矿泉水.
买5送1,每瓶矿泉水2元,
也就是10块钱能换6瓶水.
40/6的整数为6,余数为4,
也就是说,买6次10块钱的能得到36瓶水,还差4瓶,
2*4=8元,一共需要花10*6+2*4=68元.
这个是花钱最少的.
另外两位芝麻的回答,是错误的,一个忘记给老师买水了,不符合题意.
另外一个多两瓶水,虽然最划算,但是也不符合题意.

解题思路：首先理解“买十送一”的意思，就是买11瓶花10瓶的钱；原价是每瓶2.5元． 45÷10=4瓶（优惠的）余5瓶，也就是45-4=41瓶需要花钱去买，所以共至少要花（45-4）×2.5=102.5（元）．

45÷10=4（瓶）…5
（45-4）×2.5
=41×2.5
=102.5（元）；
答：一共至少要花102.5元钱买45瓶这种饮料．

点评：
本题考点： 整数、小数复合应用题．

考点点评： 解答此题，关键要理解“买十赠一”的含义，就是45里有四个10就可以赠4瓶．

一共卖出200+80=280千克
还剩：380-280=100千克

苏果超市：
3÷（1+3），
=3÷4，
=75%；
当购买到3瓶、6瓶、9瓶…这些3的倍数时时，现价是原价的75%，就是七五折出售；
华联超市：1-25%=75%；
现价是原价的75%，就是七五折出售；
两家折扣相同，但是苏果超市要购买到3瓶的倍数时才有优惠，所以到华联超市购买．
故选：D．

(116.5+18.5)÷（16-7）=135÷9=15（千克）
