Take the following as truth: Consequently it is necessary to adjust the percentage of delivery costs for these posts to the level it would be with six deliveries per week (as in the U.S.) When the percentage of delivery cost is increased or decreased for a given post, the percentage of mail processing cost is decreased or increased accordingly.
Then the following statement: "Delivery costs stay the same regardless of the percentages." is true, false, or inconclusive?
Answer: False
