Question

A coffee shop sells coffee to about 500 people every morning, but this can vary by as many as 60 people. On any given day, what are the maximum and minimum numbers of people expected to buy coffee?

Answer 1

Answer:

440 ≤ x ≤560

Step-by-step explanation:

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