Pg. 167 Update

Hi folks,

Apologies in my video earlier I made a mistake in Q4 giving the details for solving the answer with two trays of muffins instead of 6.  Anyone that has already completed it don't panic, just if anyone is confused later on when the solutions are uploaded.  Reviewed video below for Q4 and Q5, as Q5 is related to part of Q4.  

​Sorry!!
