Alana, a newly graduated student, just moved to a new city to start her first job. In order to assist her with moving expenses, she applied for a credit card. According to its terms, for any payment she makes within a month from the date of purchase, she will be charged no interest; however, if she does not pay off the full balance, interest will be charged daily on the remaining balance effective from the date of purchase. Every month she must make a minimum payment.

On May $01,$ Alana spent $$1850$ of her $$2000$ credit card limit buying furniture for her new apartment. She didn$$t make any other purchases in the month of May.

a$.$ On June $01,$ Alana made the minimum payment of $$35$ that was charged on her credit card. After her payment, interest took effect, and her new balance was $$1845\mathrm{.}77.$ What is the nominal interest rate of her credit card compounded daily?

Round your answer to two decimal places, and use this rounded value for the remainder of the case.

b$.$ What annually$-$compounding rate is equivalent to her daily$-$compounding credit card rate?

c$.$ Alana made no further purchases in the months of June and July, and made the minimum payments of $$35$ on July $01$ and August $01.$ What will be her credit card balance on August $01,$ after her minimum payment? $($Hint: Create a timeline diagram showing the payment dates.$)$

d$.$ Alana was beginning to grow concerned about her growing debt, and wanted to fully pay off her credit card. What three equal payments, on September $01,$ October $01,$ and November $01,$ must she make in order to settle her debt?

e$.$ After settling her debt on November $01,$ how much did Alana pay in interest towards her credit card since May $01?$
