Of the 20 sandwiches prepared by Ali, Ben and Carla, Ali made a total of A) two sandwiches

Information of the problem:

  • Total of sandwiches: 20
  • Ali = x
  • Ben = 3x
  • Carla = 2*(3x)

To solve this problem we have to state the equation using the information of the problem:

Total of sandwiches = Ali + Ben + Carla

20 = x + 3x + 2*(3x)

20 = x + 3x + 6x

20 = 10x

x = 20 / 10

x = 2

Substituting the (x) value into the information of the problem we get:

Ali = 2 sandwiches

Ben = 3*2 = 6 sandwiches

Carla = 2*(3*2) = 2*6 = 12 sandwiches
