Question 717661
<font face="Times New Roman" size="+2">


You are going to charge the customer *[tex \LARGE x] dollars and the credit card processor is going to take *[tex \LARGE 0.0829x] away from that amount.  You want the net to be $1000.  So:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ -\ 0.0829x\ =\ 1000]


Which is to say:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ =\ \frac{1000}{0.9171}\ \approx\ $1090.39]


Are you asking this to answer a math class problem or are you really running a business?  I only ask because if you are really running a business and your credit processor is charging you 8 and a third percent, you need to find a new credit card processor.  Even if you are keying in the number (as opposed to swiping the card) and your transactions are non-qualified you shouldn't be paying more than 4.5%.  If you are swiping and the transactions are qualified, it should be more in the range of 1.5 to 2%.
