Suppose your friend is thinking of opening a new restaurant, and hopes to have around 22 groups of (on average) 5 customers on a typical busy evening. Each meal will take around 1.6 hours and it is expected that on average a table will be used twice in an evening. Each table and its surroundings will require 4.6 square metres of space. Assume customers arrive in two streams (e.g., at 5 pm or at 7 pm). a. Calculate the required seating area. (Round the final answer to 1 decimal place.) Seating area m2 b. If each meal will take an average of 12 minutes to cook on a heating element, and each stove will have 4 elements, how many stoves would the restaurant require? Assume that all 11 "tables" could come at the same time and that the kitchen should be able to cook the meal for them during the first hour of their visit. (Round the final answer to the next whole number.) No. of stoves
