They ask you to solve for s(20) and by s = 100, they mean s(p)=100 since s is a function not a variable , so they say when p = 10, s=100 or s(10)=100
So I'm playing around with SAT questions and I stumble upon this.
After about an hour of trying I can't seem to get it right:
Question: http://s3.postimage.org/wel17i1cj/bugproblem.png
So I read the explanation which infuriated me (or perhaps made me feel very stupid, we'll see).
Am I right when I say that they are asking you to solve for ? They then go on to say that which is all fine and dandy but then the function would read: right? Which makes no sense.
It's like saying: '' , where f is the number of units sold and x is the price'', which makes no sense what so ever since denotes a function (same as in their example).
I'm really confused and a little sleep deprived so bear with me...
