Suppose the function p= -1/8 x + 100

(0 =< x =<12) relates the selling
price p of an item to the quantity x
that is sold. Assume that p is in
dollars. What is the maximum
revenue possible in this situation?

1 answer

revenue is basically selling price - cost price , ignoring some other factors

I see an equation for the selling price, but no information about the cost.
