mash [69]
First, we calculated the discounted price which would have been paid by Keith. That is the product of 85% and $36,000.
                                      ($36,000) x (85%) = $30,600
Then, after negotiating to pay 9% off the sale price, he will only need to pay 91% of the sale price. The new price would be,
                              ($30600) x (0.91) = $27846
Thus, Keith will only need to pay $27,846.
