Daryl has a total of 160 National Football League (NFL) trading cards from both the American Football Conference (AFC) and the National Football Conference (NFC). The number of AFC cards is 8 more than three times the number of NFC cards. Which system of equations can be used to find how many AFC cards, A, and NFC cards, N, Daryl has?
A.
A = 3N
A - 160 = N

B.
A + N = 160
A = 3N + 8

C.
A + N = 160
N = 3A - 8

D.
A - N = 160
N = 3A + 8
