The following situation involves a rate of change that is constant. Write a statement that describes how one variable changes with respect to the other, give the rate of change numerically (with units), and use the rate of change rule to answer any questions. The water depth in a lake decreases at a rate of 8 inches per week because of evaporation. How much does the water depth change in 4 weeks? In 12 weeks? (3 Time varies with respect to the water depth with a rate of change of 8 in./week. Time varies with respect to the water depth with a rate of change of 8 week/in. The water depth varies with respect to time with a rate of change of - 8 week/in. 53.0.0\"? The water depth varies with respect to time with a rate of change of - 8 ianeek. How much has the water depth changed after 4 weeks? The water depth has |:| by :l inch(es). (Type an integer or a decimal.) How much has the water depth changed after 12 weeks
