标题: 我好笨啊,这句话是啥意思啊,我都看不懂

With Proposition 13, if you bought your house 11 years ago for $75,000, your property tax would be approximately $914 a year (1 percent of $75,000 increased by 2 percent each year for 11 years); and if your neighbor bought an identical house next door to you for $200,000 this year, his tax would be $2,000 (1 percent of $200,000). Without Proposition 13, both you and your neighbor would pay $6,000 a year in property taxes (3 percent of $200,000).

"1 percent of $75,000 increased by 2 percent each year for 11 years"

这句话是啥意思啊? 怎么会结果是$914呢?

1 percent of $75,000 = $750
"increased by 2 percent each year for 11 years"
the tax = $750+ 750*(2% x 11)=750+165=915

这是个复利的问题，是说750每年按2%增长，所以第一年是750，第二年是750×1.02，第三年是750×（1.02）^2。。。类推，十一年后是750×（1.02)^10，约等于914。

第 3 楼
750×（1.02)^10 =933
increased by 2 percent each year for 11 years 不是复利
