对不起我真的是怂在这里了,无论如何我都算不出来1/5. 请各位CDer帮我指点。快成深井冰了。。。。。
Alice's take home pay last yer was the same each month, and she saved the same fraction of her take home pay each month. The total amount of mney that she had saved at the end of the year was 3 times the amount of that potion of her monthly take home pay that she didn't save. If all the money that she saved last year was from her take home pay, what fraction of her take home pay did she save each month? |
