Final answer:
The student's question involves mathematical computation of water costs for a hotel's usage, based on the given half-yearly water rates and the hotel's consumption.
Step-by-step explanation:
The question pertains to calculating the usage costs based on the water rates provided for a commercial user, which in this case is a hotel. To solve this problem, one would need to understand the rates structure for the half year and then multiply it by the volume of water consumption given, which is $1825m^3$. Moreover, understanding the context in which water is used can provide real-world relevance to the mathematical problem. The data and figures provided give insights into water usage trends over time and the importance of water as a critical resource. It also emphasizes the need for efficient water management in both domestic and commercial settings, given the projections of future water scarcity and the pressing need for conservation.
