Processt I thought of every combination of bales. I ended up getting ten different combinations. The weights are listed in order of numbers not in order of weight in pairs of bales. So I knew I needed to figure out the heaviest and the lightest bales..The smallest combination of bales is 80 so I will divide that by 2 and I get 40 so I know that both numbers will be around 40 I switched the numbers 1-5 for the variables a-e. So a=1, b=2, c=3, d=4, and e=5 a + b39 + 41 = 80a + c39 + 43 = 82a + d39 + 44 = 83a + e39 + 47 = 86b + c41 + 43 = 84b + d41 + 44 = 85b + e41 + 47 = 88c + d43 + 44 = 87c + e43 + 47 = 90 d + e44 + 47 = 91SOLUTION: The weight of the bales of hay is 39, 41, 43, 44, and 47. I know that I am right because all of the combinations work out so that they all fit exactly right and if you added any 2 bales of hay together they would equal one of the combinations witch are 80, 82, 82, 84, 85, 86, 87, 88, 90, and 91.
Self Assessment:I would give myself a 90 on this pow because i put good efort into it. Also I showed all my work.
