Re: [計量] pp3
我認為最偷懶的方法是 "切一半"
假設5000投資4% 5000投資6%
則利息可以拿到
5000 * 0.04 + 5000 * 0.06 = 200 + 300 = 500 < 520
所以6%的會投資的比較多
※ 引述《YYJhong (汲汲於生)》之銘言：
: Part of a $10,000 inheritance was invested at 4 percent
: and the remainder was invested at 6 percent. The total
: simple annual interest earned on the $10,000 at the end
: of one year was $520.
: Column A Column B
: The amount invested The amount invested
: at 4 percent at 6 percent
: 答案是 B
: 有人知道怎嚜解嗎
: 謝謝
