A total of $60,000 was invested for one year. Part of this amount earned simple annual interest at the rate of x percent per year, and the rest earned simple annual interest at the rate of y percent per year. Ifthe total interest earned by the $60,000 for that yearwas $4,080, what is the value of x ?
(1)x=3y/4
(2)The ratio of the amount that earned interest at the rate of x percent per year to the amount that earned interest at the rate of y percent per year was 3 to 2.
提问呀提问 这题看不明白
既然一直一部分钱用于投资且年利率为x，剩下的投资年利率为y
那已知xy比例，本金总数，以及利润总数的情况下，不就可以求出x y分别是多少了吗？
感谢感谢
