Interest rate?

Joseph bought a stereo system on his credit card on May 14th for 2759.43 his due date is May 27th. The interest rate is 19% he does NOT make any payments. How much interest would he be charged until his due date?|||Just use the standard formula:





Interest = principal x Rate x time





(I = PRT)





Just plug in the numbers/values where they appear in the formula and solve for the Interest rate amount needed.





Good Luck!|||glad to be of help...I'm a college math tutor...
