The World's Greatest Solvable Problem

The price tag for solving hunger is also less than you may realise:

- US 20 cents: the cost of one super-healthy ration of Plumpy’Sup for a small child, less than the cost of a US postage stamp
- US $10: the costs to feed a boy in a Kenya refugee camp for 3 weeks, less than the cost of a lipstick bought in Manhattan
- US $50: the cost to feed a schoolgirl for one year, roughly the same price for an iPod shuffle
