To find the answer we have to slowly analyze the command.
 For surely on the one side we want to have total cash spent, so 80.8$
We know that there are 2 types of frames 5,80$ and 9.60$.
We know too, that f is the number of frames 5.80$ bought.
Simply, to find the cash spent on those frames we have to just mulitply 5.80$ times f, so we obtain f*5.8.
We can say that number of bigger frames is 20-f.
So to find cash spent on bigger frames we have to multiply 9.60$ times (20-f), so
9.60*(20-f)
Now we can just add cost of all frames together
f*5.80+9.60(20-f)
And we know that is equal to 80.8, so
f*5.80+9.60(20-f)=80.8

As we can see, the answer is b.
