Answer:
440 ≤ x ≤560
Step-by-step explanation:
- |x−500|≤60
- Rewrite it as a compound inequality−60≤x−500≤60
- Solve for X by adding 500 to each side. -60+500≤x-500+500≤60+500
- Leaving you with 440≤x≤560
- Answer: The coffee shop is expected to serve a maximum of 560 customers and a minimum of 440 customers per morning.
