一套作文书原价60元,打了7折,一套童话书,原价40元,打6折,一共打了几折小亮在网上买了一套作文书,原价60元,打7折,又买了一套童话书,原价40元,打6折,小亮在网上买书相当于一共打了多少折?
一共打了多少折,相当于求实际出的钱占原价的百分之几.实际出的钱由60*70%+40*60%=66元;而原价=60+40=100元.所以66/100=66%=6.6折.
∵作文书现价为60×0.7=42元,童话书现价为40×0.6=24元
(42+24)÷(60+40)=0.66∴一共打了六六折望采纳:)
60*70%=42 40*60%=24 60+40=100 42+24=66 66/100=66%=六六折
好像是6.6折
啥?两个根本不是一种物体。。。

[解题过程] 作文如何写得新颖? 一、选材要新. 什么样的题材叫新? 我想题材新,主要是反对材料的千篇一律、百人一面. 比如写《我的某某同学》这个题目,如果所有的同学都是写“助人为乐”、“勤奋学习”这些事情,就显得很空洞、乏味.又比如《记...
