Final answer:
In the equation provided, the number of liters of water you drink (l) is the dependent variable and the number of times you drink all the water in your bottle (b) is the independent variable, with l depending on b.
Step-by-step explanation:
In the equation l = 0.5b, where l represents the number of liters of water you drink and b represents the number of times you drink all the water in your bottle, the dependent variable is the number of liters of water you drink (l), and the independent variable is the number of times you drink all the water in your bottle (b). This is because the amount of water consumed (in liters) depends on the number of times the water bottle is finished. The more often the bottle is emptied, the greater the total volume of water consumed. To convert volumes to the same unit for easier calculations, simply multiply or divide by the conversion factor (e.g., 1 liter is equivalent to 1000 milliliters), which assists in finding the total amount of liquid in liters and milliliters.
