Answer:

You need to rent  14  videos, and you'll pay the same amount for both. Renting 15 will make the membership a better method of payment.

Step-by-step explanation:

Let Number of videos to be rented be x;

Given:

For non members;

Cost of renting 1 video = $4

Cost for renting x videos = 4x

For Members;

Membership cost = $21

Cost of renting 1 video =  $2.50

Cost of renting x video =  2.5x

We can create an equation. Say the number of videos you rent is given by x . We can write that, if we rent  x  videos without membership, we'll have to pay 4x . If we rent the same amount of videos with membership, we'll have to pay 21+2.5x.

Hence the equation can written as

4x=21+2.5x\\4x-2.5x=21\\1.5x=21\\x=\frac{21}{1.5}=14

Hence You need to rent  14  videos, and you'll pay the same amount for both. Renting 15 will make the membership a better method of payment.
