A technician charges $25 per hour plus $50 per hour for a house call to repair home computers. Make a table and a graph to show the cost for one, two, three, and four hours of home computer service repair. Is there a direct variation?

Respuesta :

The graph starts at $75 since the price for call is $50 and 1 hour of work costs $25.

Direct variation is only noticeable at the beginning of the graph after that the function is linear.

I hope the answer helps.
