Assuming the pattern continues,write an equation to define A(n), the amount of money on the rental card after n rentals



Answer :

the answer to this question is 175 - n x 2.75

The equation that defines the amount of money on the rental card after n rentals is $175 - $2.75n.

The first step is to determine the rate at which the card value declines after a movie is rented.

Rate of decline = value of the card before the movie is rented - value after the movie is rented

$175 - $172.25 = $2.75

The equation that defines the amount of money on the rental card after n rentals is:

A(n) = beginning balance - (rate of decline x number of movies rented)

$175 - $2.75n
