问题如下：
In a CAPM that regresses Wells Fargo on the market, the coefficients on monthly data are a = 0.1 and b = 1.2. What is the expected excess return on Wells Fargo when the excess return on the market is 3.5%?
选项：
解释：
The expected return is 0.1 + 1.2 * 3.5% = 14.2%. This value is the fitted value from the linear regression when the excess return on the market is 3.5%.
不是说考试时给百分号的直接用百分号前的数字去计算嘛，怎么跟何老师上课讲的不一样，考试最终用什么比较好

根据CAPM模型E(Rp )- Rf = β [E(Rm)-Rf ] 得出E(Rp )-0.1=1.2*(3.5%-0.1) 为啥答案没有减去0.1呢？
看了答案还是不懂
