Creo que la moraleja de la historia no es demasiado agradable. La razón por la que creo que la historia se basa en ese aspecto es que el camello al final de la historia actúa de manera egoísta. El camello solo se preocupa por si mismo. Al camello no le importa lo que el maestro siente. El camello aprovecha la simpática personalidad del maestro.

The camel does not care what the teacher feels. The camel takes advantage of the sympathetic personality of the master.*
Explanation: Cuanto means How much in english, so the question is asking how much those books are going to cost. Whenever you see a Cuanto in a question like that, assume it's talking about a number of something, or money. So Cuestan means cost, in the terms of "How much does this item cost?".
