Alicia 每小时赚 $20，其中 $1.45\%$ 被扣除用于支付地方税。Alicia 的工资每小时有多少美分用于支付地方税？

(A) 0.0029 0.0029

(B) 0.029 0.029

(D) 2.9 2.9

(E) 29 29

Answer

Correct choice: (E)

正确答案：（E）

Solution

$20$ dollars is the same as $2000$ cents, and $1.45\%$ of $2000$ is $0.0145\times2000=29$ cents. $\Rightarrow\boxed{\mathrm{(E)}\ 29}$. Since there can't be decimal values of cents, the answer must be $\Rightarrow\boxed{\mathrm{(E)}\ 29}$.

$20$ 美元等于 $2000$ 美分，$2000$ 的 $1.45\%$ 是 $0.0145\times2000=29$ 美分。$\Rightarrow\boxed{\mathrm{(E)}\ 29}$. 由于美分不可能是小数值，答案必为 $\Rightarrow\boxed{\mathrm{(E)}\ 29}$。
