d. Alana was shocked by how long it would take for her to pay off
her debt if she continued to only make the minimum payment of
$20, and so she made a plan to be debt-free in six months. What
equal payments would she have to make at the end of each
month (starting on June 30) in order to achieve this goal?
e. If she followed her payment plan laid out in (d), what would the
balance be on Alana's credit card after her third payment
(halfway through her repayment plan)?
f. If on November 30, after making her final payment, her credit
card balance is $0, how much interest did she pay towards her
credit card since November 30 the previous year?
