Number 3: need more info
Number 4: is 337.5.
- first we need i\to find how much one case costs. $45/2 = $22.5
- next multiply $22.5 x 15 which gets you $337.50
Number 5: is 65%
- 100% divided by 3,100 is .03225806
- then multiply .023225806 by 1085 which gets you 35%
- but because it is asking for the remaining it is 100% - 35% which is 65%
All you need to do for this is remove the parenthese and your answer will be 
because that's the furthest it can be simplified.
I believe it is 8,459,999,894,000,001
