We have 4 types bottles of water. Bottle 1 - with capacity 750ml - we have 2 for use with price 0,25 Bottle 2 - with capacity 500ml - we have 3 for use with price 0,5 Bottle 3 - with capacity 250ml - we have 5 for use with price 0,75 Bottle 4 - with capacity 100ml - we have 10 for use with price 1
Using water from these 4 types of bottles we have to create "aqueous mixture" containing 3050ml of water in total.
How we should pour water from those bottles that cost as low as possible and to have the least possible loss of water.
How to solve this?
