Arezo borrowed $2,500 from her grandfather. This graph shows the balance remaining on Arezo’s debt after she makes each payment. Using this graph, how much will she owe after 4 payments?

Answers

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.

y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)   ----A

(x_1,y_1)=(0,2500)

(x_2,y_2)=(1,2000)

Substitute the values in A

y-2500=(2000-2500)/(1-0)(x-0)

y-2500=-500x

y=-500x+2500

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

y=-500(4)+2500

y=-2000+2500

y=500

Hence she will owe $500 after 4 payments.

Answer:

She will owe $500
