Question

Video club members pay an annual membership fee of $25.00, which allows them to rent movies for $3.50 instead of $5. What is the least number of videos that a club member must rent during a year to save money from the membership?

 

We are currently learning about linear equations if that helps at all.

Answer 1

let x be the number of videos rented so that you pay the same amount with or without membership.

 

$25.00 + ($3.50)x = ($5.00)x

 

$25.00 = $5.00x - $3.50x

 

$25.00 = $1.50x

 

x ≈ 16.67

 

you have to rent at least 17 videos to save money.
