Problem 2
th the use of three different weights, namely 1 lb., 3 lb., and 9 lb., how many objects of different weights can be weighed, if the objects to be weighed and the given weights may be placed in either pan of the scale?
***Clarification*** Only the three weights and the one object being weighed maybe be used (i.e. no previously weighed objects), but that doesn't mean you have to use all three weights at once. You are free to use one, two or three of the weights.
