Practice Question
For an emergency service call, a plumbing company charges a flat fee of $60 plus $40 an hour. A customer remembers paying at least $200 for an emergency service. Which phrase describes the number of hours the plumbing company was at the service call?
Answer Choices
- A: at most 2 hours
- B: at most 3.5 hours
- C: at least 3.5 hours
- D: at least 2 hours
Correct Answer: C
Rationale: Set up the inequality: 60 + 40h ? 200. Subtract 60: 40h ? 140. Divide by 40: h ? 3.5. Thus, the number of hours is at least 3.5 hours. The correct answer is at least 3.5 hours.
