Allison has 5 times as many baseball cards as football cards. in all, she has 120 baseball and football cards. how many baseball cards does she have ?

B = 5*F OR

A) B -5*F = 0

B) B + F =120

B) B + F =120

Adding both equations

6 F = 120 so F= 20 football cards and there are 100 baseball cards.
