16 cm

Step-by-step explanation:

The curve shows displacement in cm. The maximum value of the curve is 16, so the maximum displacement is 16 cm.

Given that there are four guests in each table, the 12 tables would have 48 guests. the restaurant desires to have at least 1 server per 48 people. the inequality that would best represent the given situation is,
                                  48x  ≥ y
if we try to substitute 1 to x and 1 for y we get, 48  ≥ 1 which is true.
