A factory produces widgets. The cost $C_A$, in dollars, to produce $x$ widgets using Method A is given by $C_A=1.5x+50$. The cost $C_B$, in dollars, to produce $x$ widgets using Method B is given by $C_B=1.2x+80$. If the factory wants to produce between 150 and 200 widgets, inclusive, what is the maximum difference in cost (in dollars) between Method A and Method B for this production range?
