A local band is selling hats (x), shirts (y), and jackets (z) at their show. One fan bought 5 hats, 1 shirt, and 2
jackets for a total cost of $277.92. A second fan bought 1 hat, and 1 shirt for $41.98, while another fan bought 3
hats, 4 shirts, and 1 jacket for $237.92. Which of the following systems represents the given information?
A 5x - y - 2z = 277.92
C 5x + y + 2z = 277.92
x-z= 41.98
x + y = 41.98
3x – 4y - z = 237.92
3x + 4y +z = 237.92
B 5x + y + 2z = 277.92
x + y + z = 41.98
3x + 4y + z = 237.92
D 5x + y + 2z = 41.98
x + y +z = 237.92
3x + 4y + z = 277.92
