I was reading Form 1 Kemahiran Hidup text book written by Zulkifli , Zainal and Tuslah, at page 352, section 3.3.3 and 3.3.4 seems to give contradicting explanation.
On page 368, question no 9, I can not find a logical way to calculate the cost of production per unit base on the theory given by the text book.
The book is the 11 release and was printed in 2006. So, it is unlikely that the book can be wrong, but I can not find any logical answer that they are indeed correct.
Anyone read that part of the book? or care to have a look to see if you can find a logical explanation?
