Unfortunately, his knapsack is too small to carry them all, so he must choose (wisely). He has made the following estimates of the objects’ weights and values.
Treasure **Weight ** Value ($) Crown of Atahualpa ** 4 lb. ** 4,000 Mask of the Ancients ** 5 lb. ** 5,000 Itzcoatl’s Orb ** 6 lb. ** 9,000 Tablet of the Heavens** 7 lb. ** 7,000 Golden Quetzal **13 lb. **17,000 Key of Silver Light ** 2 lb. ** 2,000 Idol of Inti **10 lb. **15,000 Eternal Quipu ** 5 lb. ** 8,000 Goblet of Uxmal ** 3 lb. ** 4,000 Sacred Stone of Cuzco** 8 lb. **11,000
If his knapsack can hold at most 20 pounds of treasure, which objects should he take to maximize the value of his loot?
