Answer:
She will owe $500 after 4 payments.
Step-by-step explanation:
With the help of graph
Number of payments (x) Balance remaining(y)
0 2500
1 2000
2 1500
Since it is linear function .
So, we will use two point slope form to find the equation for the given situation.
----A
Substitute the values in A
Where x is the number of payments
y is the remaining payment
This equation represents the given situation.
So, to find the amount remaining after 4 payments .Substitute x =4
