You can put this solution on YOUR website!
%2868%2B68%2B%2868-15%29%29%2Ax=1099 looking at groups of three chairs discounting to one of them; x number of these groupings.
189x=1099
x=5.8148

Expect about five of these groups of three to work.
5%2868%2B68%2B68-15%29
5%28204-15%29
945-------------the cost for 15 chairs.
945%2B68=1013---------cost for 16 chairs.
1013%2B68=highlight_green%281081%29---------cost for highlight%2817%29 chairs
Buy no more than that.
