Question 1151432: It took her 9 more months but Marina has managed to save the full $750 plus more to cover fees to pay off the pay-day loan company. However, she forgot to account for the interest that had been compounding over time. Consider it is now 275 days later, the remaining loan was $750 and the APR is 47% compounded daily.
What is the total amount that Marina must now pay in order to pay off her the loan, accounting for interest?

Question 1151434: Anna was pretty disappointed with how little money she would have and so she started looking at other investment options that involve higher risk but would also offer more possible return. Her bank’s financial advisor suggested a mutual fund the she said was only moderately risky but had a record of 9.5% annual return.
Assuming the mutual fund preformed as well as it has in the past, how much would Anna’s investment of $2500 potentially be after 4 years if she decided to go with this option?

Question 1151431: The end of the month has arrived and Marina was only able to save up $150 to pay off her pay-day loan of $900. This means she will have to delay payment on the remaining $750. Besides the delayed payment fee that she is charged, she will now have to pay interest on the remaining amount. The APR (annual percentage rate) is 47%, but the interest is compounded daily.
What is the effective interest rate that Marina will actually be paying?
