Hello Justus,
In the text is written that
A consolidation of suppliers reduces transport costs by EUR 4 million (EUR 20 million * 20%)
As you may notice, the author talks about a reduction of costs 4M€, It means that, as you were suggesting, the new cosi is: Original cost - Reduction = 20M€ - 4M€= 16 M€.
Does it make sense?
Best,
Luca
Hello, i think that the 20% should be applied to the cost of transportation of the new sales volume which is 501,5 M. Therefore, the cost reduction will be 20% * 501.5*0,03 = 3M. 0,03 being the transport cost per sale. Am I wrong? — Marwane on Jun 09, 2020 (edited)
Hello!
Indeed!
The 20% is precisely 4 M, so the new figure is 16 (20 - 4 = 16 M)
Cheers!
