[size=200][b]Part 2[/b][/size]

[size=100][b]5) Graph a model for Business B such that Business B has a higher number of products initially marketed and such that Business B markets products more slowly than Business A.[/b][/size]

[size=100][b]6) Graph a model for Business C such that Business C has zero products initially marketed and such that Business C markets products three times as quickly as Business A.[/b][/size]
