The coordinate grid below shows the graph of supply and demand functions for the sales of wooden chairs. For the
functions, x represents the number of chairs, in hundreds,
and y represents the price of each chair, in dollars.
The equilibrium point for the functions can be found by
locating the point where the two functions are equal. Which
of these appears to be the number of chairs, in hundreds,
that must be sold to achieve equilibrium?
