The combined weight of all the samples can simply be calculated by the arithmetic sum of all the individual weights of each sample.
The total <em><u>combined weight</u></em><em> </em>of all the samples is "114.22 lb".
Adding the individual weights of each sample we get:
Combined weight = Weight of sample 1 + Weight of sample 2 + Weight of sample 3
Combined Weight = 31.2 lb + 38.02 lb + 45 lb
<u>Combined Weight = 114.22 lb</u>
