At a restaurant the cost for a breakfast taco and a small glass of milk is $2.10. The cost for 2 tacos and 3 small glasses of milk is $5.15. Write a system of equations that represents this situation.

• t - m = 2.10

  2t + 3m = 5.15

• t + m = 2.10

  2t + 3m = 5.15

• t + m = 5.15

  2t + 3m = 2.10

• t - m = 5.15

  2t - 3m = 2.10
