For a TH9, you have 7 gold, 7 lix, and 2 dark collectors - total 16. They cost 10 gems each to boost for 24 hours, so that is 160 gems. The resource potion costs 115 gems.
The training boost costs are 30 for barracks, 10 for spells, and 5 for each hero, so a total of 45-60 depending on how many heroes you have. That potion costs 25 gems.
Each item is always offered at the same price (except when a freebie). Different players get different items offered, but anyone who is offered a (non free) training potion will be offered it for 25 gems, anybody offered wall rings will be getting 2 for 400 gems.
