Caitlin has a movie rental card worth $175. After she rents the first movie, the card’s value is
$172.25. After she rents the second movie, its value is $169.50. After she rents the third movie,
the card is worth $166.75.
Assuming the pattern continues, write an equation to define A(n), the amount of money on the
rental card after n rentals.
Caitlin rents a movie every Friday night. How many weeks in a row can she afford to rent a movie,
using her rental card only? Explain how you arrived at your answer.
where a is the amount on the card 175 is the original amount in the card 2.75 is the cost of a movie rental times n amount of rentals ------------------------------------------------------------------------------- n=175/2.75 =63.63 =63
