Question

Ben works as a dishwasher at the Park Street Banquet Hall. Before an event he must wash 10 salad plates for each table that is being set up in the hall. Depending on the event, the hall will set anywhere from 20 to 50 tables. The function P(n) represents the number of plates Ben must wash for an event with n tables.
What is the range of P(n)?
Real or Whole numbers

Answer 1

P(n) = 10n with 20 ≤ n ≤ 50, so 200 ≤ P(n) ≤ 500.

Since n (tables) is an integer, P(n) takes whole-number values (specifically the multiples of 10):
{200, 210, 220, …, 500}.
