Maya and Anthony were at their local grocery store purchasing items for a barbeque. Maya decided to buy 6 cans of beans and 4 cans of corn for $28 Anthony opted for 1 can of beans and 6 cans of corn for $20. Write a system of equations for this situation.

• 6x + 4y = 20

  x + 6y = 28

• 6x + 6y = 28

  x + 4y = 20

• 6x + 4y = 28

  x + 6y = 20

• 4x + 6y = 28

  x + 6y = 20
