Here goes. I have to achieve the highest number possible equal to or less than 143. 143 is the ideal number, anything above that is of no use. The numbers I have to work with are 37, 73, 44, 44, 40, 52, 73, 34 and 39. The closest I've managed to get is 140 combining 44, 44 and 52. Can anyone find anything higher than 140 or another combination that makes 140? Thanks for your help.
