At a college bookstore, Carla purchased a math textbook and a novel that cost a total of $54, not including tax. If the price of the math textbook, m, is $8 more than 3 times the price of the novel, n, which system of linear equations could be used to determine the price of each book?

• m + n = 54

  n = 3m + 8

• m + n = 54

  n + 8 = m

• m + n = 54

  m = 3n + 8

• m + n = 54

  m + 8 = n
