Question

The local video store charges a monthly membership fee of $5 and $2.25 per video. write a rule as an algebraic expression to model the relationship. Please answer fast. I have a thought in my head but i just want to make sure

Answer 1

In solving this problem, $5 will be a fixed cost and $2.25 will be a variable cost, depending on the number of videos rented in a month. If you signify the number of videos rented in a month as V, and your total price per month as P, the algebraic expression

5+2.25V=P

will be a model of the relationship.

You will need to know how many videos you rented to solve the equation; however if the question is asking you for an algebraic representation this should be sufficient.
