2. The municipality of Charlesburg records an average daily water consumption of 998 L per household using an unmetered distribution system. The town decides to install water meters at a rate of 100 households per month. After six months, an analysis shows the line of best fit for the average consumption, C, per household, versus the number of meters installed, n, has the equation C= -0.358 n +996. What is the predicted consumption per household after 1000 meters are installed?
