Answer:
The initial value is $10.45
The rate of change is
Step-by-step explanation:
Let
m-----> the the monthly fee
we know that
Solve for m
<em>Find the linear equation that represent this problem</em>
Let
x -----> the number of months
y-----> amount Jeanne has spent monthly
The equation in slope intercept form is equal to
where
m is the slope (the monthly fee)
so
Remember that
The first month, she paid the monthly fee and spent an additional $10.45
For x=1, y=5+10.45=15.45
substitute
The equation is
therefore
The initial value is $10.45
The rate of change is the slope of the linear function
