Sevastion's friend gives him 4 special baseball cards to start his own collection . Sebastian then buys 6 new baseball cards for
his collection every month. If x is the number of months , what is the linear function of f (x) , that represents the total number of baseball cards in sebastians collection as a function of the number of months
if we take the number of quarters Barrett have to be x we know Penelope has twice that ie 2x. so in total they have 2x+x = 60, 3x = 60; so x= 60/3 = 20.
