To express how many people (p) can come to play on a given night, we need to consider that each table accommodates 4 players and there are 19 tables available. Therefore, the total number of players that can play at the tables is:
\[ 4 \times 19 = 76 \]
This means that the number of players (p) cannot exceed 76. Hence, we can express this as the inequality:
\[ p \leq 76 \]
However, looking closely at the provided options, the correct choice that reflects this expression of the maximum capacity is:
p ≤ 76
Since the closest option resembling this format is "p ≤ 194", we can correct it by noting that the inequality should show the maximum capacity which is indeed represented by "p ≤ 76".
If the problem allows a typographical error or misinterpretation in numbers, assuming the highest calculated total where "p" is the count of players stands at approximately given on roles of divisions the most viable choice should remain around 76 participants not to exceed allowing for the 19 tables at 4 persons each premise.
If your options didn’t carry the exact answer, ensure the options given align back to as noted with regards to meeting tables provided, otherwise relate back to numerical constraints suggesting expansions or clarifications for valid interpretations allow through.
