Question

Ellen has a movie rental card worth $225. After she rents the first movie, the card’s value is $221.75. After she rents the second movie, its value is $218.50. After the third rental, the card is worth $215.25. Assuming the pattern continues, write an equation to define A(n), the amount of money on the card after n rentals. Ellen rents a movie every Saturday night. How many weeks in a row can she afford to rent a movie, using her rental card only?

    Answer:

    69 times

    Step-by-step explanation:

    $225 – $221.75 = $3.25

    $221.75 – $218.50 = $3.25

    … etc

    Therefore pattern is 3.25

    Need to find how many times $3.25 can be taken from $225

    So

    $225/$3.25 = 69.2 times

    69 times (whole number)

    Answer: She can rent 69 weeks in a row(assuming its counting from the inital value which is 225)

    Step-by-step explanation: The equation would be A(n)=225-3.25^(n-1). I think thats the equation, im not sure since it has been a few years since i did these kinds of questions.
