如果有以下这道题目，用TI BAII plus的计算器能不能一步算出来？
An investor has a portfolio with 10 percent cash, 30 percent bonds, and 60 percent stock. Last year, the cash returns was 2.0 percent, the bonds?return was 9.5 percent, and the stocks?return was ?2.5 percent. What was the return on the investor抯 portfolio?

这个还是一步步算，即使可以一下子算出来，你也要记忆计算的步骤，不合算
