From the graph, P(x) is 137.5 thousand dollars when x is 4.5 or 7.5 hundred dollars.
That is
137.5 thousand of dollars = 137.5 x $1000 = $137500
4.5 or 7.5 hundred dollars is 4.5 x $100 or 7.5 x $100 = $450 or $750
Therefore, if the company wants to make a profit of $137500, then the price of the bicycle should be $450 or $750
