An electrician charges $60 to come to your home, plus $35 per hour of work. During one week, he visited 8 homes, and his total income was $1,880. How many hours did the electrician spend working?

$60 per home x 8 homes = $480

1880-480 = 1400

1400/35 per hour = 40 hours

He worked a total of 40 hours.
