@Hero ...how are you supposed to do this if their is no constant difference ?

anonymous · Answer

You are not getting 42.75 per hour

hero · Answer

It must be a linear function

anonymous · Answer

a proportion won't work, will it ?

hero · Answer

You have two points:

(1, 42.75)
(5, 260.75)

Graph that. Find the slope and create an equation for the line.
