Teddy bought 15 tickets to a movie, where adult tickets cost $6.00 and senior citizen tickets cost $4.00. He spent a total of $76. Which system of equations will determine the number of adult tickets, a, and the number of senior citizen tickets, s, Teddy purchased?

• a + s = 15

  10as = 76

• a + s = 15

  6a + 4s = 76

• a + s = 15

  4a + 6s = 76

• a + s = 15

  a + s = 76

• a + s = 76

  6a + 4s = 15
