现在100元放到两年后=106...
牛逼!
It follows that if one has to choose between receiving $100 today and $100 in one year, the rational decision is to cash the $100 today. If the money is to be received in one year and assuming the savings account interest rate is 5%, the person has to be offered at least $105 in one year so that two options are equivalent (either receiving $100 today or receiving $105 in one year). This is because if you have cash of $100 today and deposit in your savings account, you will have $105 in one year.
equivalent这个英文懂不懂什么意思?,不懂就去问问你的老师
