At a college bookstore Carla purtidsed 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, which system of linear equations could be used to determine the price of each book?
Answer provided by our tutors
m = the price of the math textbook
n = the price of the novel
The system of equations used to determine the price of each book is:
m + n = 54
m = 8 + 3n

........
m = $42.50
n = $11.50
The price of the math textbook is $42.50.
The price of the novel is $11.50.
