An emergency plumber charges $49.00 plus $70.00 per hour of the repair. A bill to repair your sink is $241.50. This can be modeled by
70.00h + 49.00 = 241.50, where h represents the number of hours for the repair. How many hours did it take to repair your sink?

Respuesta :

2.75 hours . 241.50-49= 192.5 / 70= 2.75
