Answer:
Independent: Number of pounds
Dependent: Cost
Rate of change: $1.99 per pound
Explanation:
In this situation, there are 2 variables: The number of pounds and the cost.
The independent variable is the variable that you decide. Since you decide how many pounds of apples to buy, the independent variable is the number of pounds.
The dependent variable depends on the independent variable. Since the cost change depending on the number of pounds. The cost is the dependent variable.
Finally, the rate of change can be calculated as:
[tex]\frac{\text{ Change dependent variable}}{Change\text{ independent variabl}e}=\frac{11.94-3.98}{6-2}=\frac{7.96}{4}=1.99[/tex]Therefore, the rate of change is $1.99 per pound.
