Answer 1

6 hours

Explanation:

dg's plumbing and heating charges $50 plus $60 per hour for emergency service. bill remembers being billed just over $400 for an emergency call. how long to the nearest hour was the plumber at bill's house?

60h + 50 > 400

subtract 50 from both sides:

60h > 350

divide both sides by 60:

h > 5.8333

rounded: 6 hours
