A minor modification that will make it more useful. Instead of
entering the target number in solver, enter in the spreadsheet. To
continue the above example,
A7 = Target Value
A8 = Variance
B7 = 54,781.43
B8 = abs(b6-b7)

In solver change "Equal to Value" to "Equal to Min" then solve.

When done, if the Variance is zero, you'll have an exact match. If it
is not zero, then you'll have the combination that is closest to the
target as possible.
