Question

The value of almost everything you own (assets), such as a car, computer, or house, depreciates (goes down) over time. When an asset’s value decreases by a fixed amount each year, the depreciation is called straight-line depreciation. Suppose your truck has an initial value of $12,400 and depreciates $820 per year. What two variables are involved in this problem? Which variable can best be designated as the dependent variable? As the independent variable?

Answer 1

Usually we consider value to be the dependent variable, and age to be the independent one.

so the answer is C.  

Independent variable - number of years you own the truck;

Dependent variable - value of the truck.

Answer 2

The independent variable is the depreciation, while the dependent variable is the value of the item.
