There are two photography stores in town that do custom film developing, Perfect Picture (abbreviated PP) and
Dynamic Developers (abbreviated DD). At PP the cost to
develop one roll of specialty film is $12 but any additional
rolls of film cost only $10. At DD the cost of developing
one roll of film is $24 but each additional roll is developed
at a cost of only $8. For what number of rolls of film is the
cost of developing the same at PP and DD?
