I know that the mix variance is calculated by computing the difference between the actual amount of direct materials and the standard amount, then multiplying by the standard price. In this case, I did:

(945-760)(5.27)=974.95 U

(55-40)(8000)=120,000 U

I'm just really confused and not sure what I'm doing wrong.
