a)     Let x = number of hot dogs sold for the month

        Let m = amount of money made from hot dog sales

        m  =  3.25(x - 4)

 

b)     m  =  3.25(55 - 4)  =  165.75

 

c)     Let x = number of hamburgers sold for the month

        Let m = amount of money made from hamburger sales

        m  =  4.75(x - 2)

 

d)     Since the number of hamburgers sold is probably not the same as the number of hot dogs sold, the work shown is           

        incorrect.

 

        You need to use  different variable for the number of hamburgers sold than for the number of hot dogs sold.

         A possible equation is:  m  =  3.25(x - 4) + 4.75(y - 2)

            where  x = number of hot dogs sold for the month

                        y = number of hamburgers sold for the month

                        m = amount of money made from the sales of both hamburgers and hot dogs.
