I think with the kinds of mixture problems, it's really helpful to make a table.
The equations you actually need are

and

. Since I was so close, I went ahead and just solved it anyway. You can see my setup on the attached image.

For this case we have an expression with two variables, the value of each one of the variables is given in order to evaluate the expression and obtain a result. To do this, we must replace the values of a and b respectively in the given expression.
Let 
and we have
and
, substituting the values of the variables we have:

Thus, when evaluating the expression with
and
we have 176.
Answer:
The result is 176
Option A
