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 allison have?

                           If Jim has x football cards He will have 5x  baseballs cards Thus           x + 5x  =  120      >    total # of cards                    6x  =  120                    x= 120/6    =   20                           so Jim has 5x baseball cards  =   20*5 =100 baseball cards
