Answer:

  • Number of bags of chips sold is 20
  • Number of fruit snacks sold is 5

Step-by-step explanation:

x = number of bag of chips sold

y = number of fruit snacks sold

y = x - 15

1.75x + 1.5y = 42.5

-->Substitute "y"

   1.75x +1.5 (x-15) = 42.5

1.75x + 1.5x - 22.5 = 42.5

         1.75x + 1.5x  = 42.5 + 22.5

                 3.25 x  =  65

                          x  = 65/3.25

                          x  = 20

--> Substitute "x"

y = x - 15

y= 20 - 15

y = 5

--> x =20     y = 5
