The revenue equation for a certain brand of mouthwash is y = 1.3x, where x is the number of bottles of mouthwash sold
and y is the total income for selling x bottles. The cost equation is y = 0.5x + 2500, where x is the number of bottles of
mouthwash manufactured and y is the cost of producing x bottles. The following set of axes shows the graph of the cost
and revenue equations.
