Final answer:
The Aztecs had a market-oriented economy with a tribute system enriching Tenochtitlán; Incas had central control over resource management, using roads for administrative control and military mobilization.
Step-by-step explanation:
The difference in the administration of the economies and trade of the Aztec and Inca Empires can be seen in several aspects. The Aztec Empire had a more market-oriented economy with various market towns where a wide array of goods could be purchased, and they used tribute as a means of integrating different regions under their control. Goods and labor from conquered territories were incorporated into their economic system, with the central city of Tenochtitlán being a major hub for tribute collection. On the other hand, the Inca Empire exercised more direct control over their economy, with an emphasis on managing resources and labor for state projects, such as the construction of their extensive road network, which was used primarily for military and administrative purposes rather than trade. The Inca rulers strategically used this network to maintain control over the vast and varied terrains of their empire and to swiftly mobilize resources and troops.
