Suppose your friend is thinking of opening a new' restaurant, and she hopes that she will have around 20 groups of (on average) 4 customers on a typical busy evening. Each meal will take around 1.5 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 square metres of space.
a. Calculate the required seating area.
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 10 “tables’' could come at tire same time and that the kitchen should be able to cook the meal for them during their first hour of visit.
