254For example cost of sales (100%)+mark up (20%) = turnover 120%

So knowing the sales and cost of sales will help us find the mark up %

Total cost of sales (fixed + variable) £14710150 and Turnover £16800000

Substitute in the formula to get £2089850

To find what percentage is that of cost : 2089850/14710150*100=14.21 rounded up

41I have one more question - I have attached the question. I am struggling to calculate the Inventory holding period. The answer is 148 days and i get 147. I would appreciate if you could explain where I am going wrong. I calculated the average of the inventory first.

thank you
