How much did the United States pay Spain for the Philippines under the Treaty of Paris?

Under the Treaty of Paris, which concluded the Spanish-American War, the United States agreed to pay Spain $20 million.12

This payment was nominally designated for public buildings and public works in the Philippines. The transfer of the archipelago was a central point of contention that ultimately led to the Philippine-American War, as the United States moved to take possession of the islands despite the existence of a provisional republic already established by Filipino insurgents under Emilio Aguinaldo.12
