Alec bought 2 nachos and 1 taco at Bueno Taco for $20.57. Josh bought 3 nachos and 3 tacos at Bueno Taco for $36.24. Which equations are true for these systems?

• n + t = 20.57

  3n + 3t = 36.24

• 2n + t = 20.57

  3n + t = 36.24

• 2n + t = 20.57

  3n + 3t = 36.24

• n - t = 20.57

  3n + 3t = 36.24
