The equation A(n)= $175 –(n x $2.75) would define the
amount of money on the<span> <span>rental
card after (n) rentals. </span></span>
<span>According to the pattern given, $2.75 will be
deducted to the rental card every after Caitlin rents a movie. We can simply
divide the amount of the card which is $175 by $2.75 which we presume the
rental fee. From that, we can have a result of 63.63 rentals using her card. Therefore,
there will be 63.63 weeks Caitlin can afford to rent a movie.</span>
