Simple interest question?

Posted at: 2014-12-05 
I don't know if I would trust this answer 100% but I guess here is my thought process:

Basically the $5 is one month's interest.

$5 = x% * $74

x = 6.75675%

Then with that being simple interest I believe you would just multiply by 12 to get an APR of 81.081%

Assuming I'm even close, I would say that the senator is right to a point. If there is no limit on your layaway and the fee is always $5, there would be a point at which the APR would be less than the 21% average APR of most commercial credit cards (about $286).

can you explain step by step? where did you get the percentage?

Hi can anyone help me out with this question:

Compute the specified quantity.

Layaway plans allow you, for a fee, to pay for an item over a period of time and then receive the item when you finish paying for it. In November 2011, Senator Charles E. Schumer of New York warned that the holiday layaway programs recently reinstated by several popular retailers were, when you took the fees into account, charging interest at a rate significantly higher than the highest credit card rates.? Suppose that you bought a $74 item on November 15 on layaway, with the final payment due December 15, and that the retailer charged you a $5 service fee. Thinking of the fee as interest, what simple interest rate r would you be paying for this layaway plan? (Round your answer to three decimal places.)

r = %
