Talk:High School Mathematics Extensions/Financial Options

The dialog is confusing because of the switch between the $3000 example and a $2000 example. If intended, there is not enough explaination. If not intended, it leaves one confused.

Also, a question comes to mind about what would happen if the price fell to $6, or $4 in an unsuccessful negotation. Would the value not also be zero? ... how is this actually handeled when it comes to simultaneous equations?
 * thanks, this module needs alot of work. the 2000 3000 disparity has been corrected thanks for pointing it out. "if the price fell to $6, or $4 in an unsuccessful negotation. Would the value not also be zero?" The example states that the price will fall to $5 if the negotiation is unsuccessful. This is fixed. Say if you want to consider if the price shall fall to $6 if unsuccessful, then you will need to solve
 * 11y + z = 3000
 * 6y + z = 0
 * instead, which yields y = 600 therefore z = -$3600, and so the option is 600*8-3600 = 1200 which is more expensive. As one would expect. Will improve with time. Xiaodai 08:32, 13 November 2006 (UTC)
