Interpreting a Linear Equation
At 12:00 P.M. the volume of water in a tank started changing steadily over time. The volume $\displaystyle {V}$ measured in gallons, $\displaystyle {t}$ minutes after the water volume started to change is given by the equation $\displaystyle {V}={7400}+{3.7}{t}$ . The equation tells us that the volume of water in the tank was initially gallons, and that the volume is by .
