这两道英文的数学题怎么做？非常急急急急急急

1）Miss Lee invested $15000 in a bank that pays 4.6% compound interest per annum compounded every three months. Calculate the total amount she has in the bank after 2.5 years.
翻译：李小姐在一家银行投资了15000元，那家银行每年支付4.6%的复利,每三个月复利一次。算出他在银行2.5年后的总金额。

2）Amy invested $30000 in an account that pays a compound interest of 12% per annum, compounded monthly. Find the interest accumulated after 5 months.
爱眉在一个银行户口里投资了30000元，那家银行每年支付12%的复利，每月复利一次。请找出5个月后累积的利息。

我可能翻译得不好，请见谅，但大概就这么意思，可以参考英文版的。
希望数学高手尽快替我解答，感激不尽啊！
