一道英语数列数学题
Cause I make payments of $250 per month,so 20 months will be spend till this loan had been paid off.
At the first month,I pay $250 and 1% interest on the unpaid balance,said $5000.That is to say,I'll pay $300.At the second month,I pay $250 of the principal and 1% interest of the unpaid balance,said $4750,$250 less than last month.
So I make this table as below.
(1) Your unpaid loan is 5000-250*(n-1)=5250-250n (1=<n<=20)
(2)The total interest will be $525.
借钱： 你从你父母那里借来5000美元用来买一辆二手车。还款计划是你每个月偿还250美元外加剩余欠款1%的利息。
a) 找出第一年的月供和每一个月末的欠款余额
b) 找出还款期间的总利息额请列出数学式子，解题过程我靠下面有牛人，用 知止萌小蘇 的吧...

(\x1da) in the nth month, your unpaid loan is 5000-250*(n-1)=5250-250n
so the first year monthly payments is 250+(5250-250n)*1%=302.5-2.5n(1=
