First find how many ml of water Jason needs for 1 gram of charcoal: 30 ml / 2 grams = 15 ml / g. Then divide the amount of water Jason uses by the amount of water per gram of charcoal to find how much charcoal he uses: 900 ml / 15 ml / g = 60 g.
The answer: 60
Reverse engineering the question: Jason is mixing a batch of black paint. He needs to add 2 grams of charcoal for every 30 ml of water. If he adds 900 ml of water, how much charcoal does he add?

Reasoning and answer: The juice was two times more expensive than the sandwich, so it was 4 * 2 = $8. The juice and the sandwich in total were a cost of 4 + 8 = $12. So the cost of one bottle of milk was 75 / 100 * 12 = $9. In total for all the food, George paid 12 + 9 = $21.
The answer: 21
