Nuts and Bolts
The distance a bolt protrudes past the edge of a nut is a linear function of the number of revolutions through which the bolt is turned.
The slope is the distance covered per revolution (in cm per turn).
The y-intercept is the opposite of the "length" of the nut.
The x-intercept is the number of turns required to make the bolt just flush with the other end of the nut.
Suppose the nut is 1 cm long and the bolt travels .4 cm per turn.

Suppose the blower and license are $750 and you charge $45 per job.
