The number of bulls sold is the same as the price received per bull (hence the amount of money they receive is a perfecrt square). With the proceeds they bought goats at \$10 each and kids at \$1 each, and the two ended up with the first trader having one more goat than the second trader, and the second trader having one more kid than the first (in other words, there are an equal odd number of goats and kids). The trader who received the extra kid instead of a goat gets \$9 compensation. Question is: what were the proceeds they received from sales of the bulls?

The problem is that there are multiple answers, none of them having to do with odd tens digits, so it seems my understanding of the problem is incorrect. For example proceeds could be \$64, in which case they buy 5 goats for 5x10=\$50 and 5 kids for 5 x \$1 = \$5, and have \$9 left over as compensation for the trader who gets 3 kids and 2 bulls. Other possibilities are \$196 and \$300. So it seems I still don't understand the question - please clarify as best you can. Thanks.

PS - if you place a backslash in front of the dollar sign then the sign will display correctly - otherwise thr forum software thinks teh dollar sign is a delimiter for LaTeX.
