4. 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?

A.

m - n = S

m = 3n - 54

C. m + n = 54

m = 3n + S

B. m = n = 8

m = 3n - 54

D. m + n = 54

m = 3n-s
