Answer:
.
Step-by-step explanation:
We are given function f for Aleka's amount

And function for Helene's amount
.
Now, we need to find the difference of the functions h(x) = f(x)-g(x).
Subtracting f(x) and g(x), function, we get

Distributing minus sign over second parenthesis, we get

Subtracting
, we get 1000.
Therefore,
.
The independent variable for this function is the number of items wrapped while the dependent variable is the cost to wrap the gifts. This is because the independent variable refers to the input to the function while the dependent variable is the output of the function. In this case, the function is expressed as:
C = 3 + 1(X)
where,
C = cost of wrapping the gifts
X = number of items wrapped
