Problem
Nadir has placed an empty egg carton on a set of scales. Its mass is 32 g. When the carton is filled with 12 eggs, the total mass of eggs and carton is 743 g.
(1) Find the average mass of the eggs in the carton.
(2) Hence write an arithmetic sequence for un , the approximate total mass when n eggs have been added to the carton.
(3) For what values of n is your model valid?
