Respuesta :

Answer:

9 DVD

Step-by-step explanation:

Let the number of DVD borrowed =x

In the first plan, the video rental company offers a plan that includes a membership fee of $8 and charges $1 for every DVD borrowed.

Total Charges for first plan= $8+($1 X x)=$(8+x)

They also offer a second plan, that costs $17 per month for unlimited DVD rentals.

Total Charges for second plan=$17

We want to find the number of DVD for which the two plans cost the same.

8+x=17

x=17-8

x=9

If a customer rents 9 DVD, the plan costs the same

The total Cost is $17
