Answer:
Step-by-step explanation:
See the attached for a spreadsheet of the values given in the problem statement. We have simply added the salary to the value of the preference and subtracted the one-time moving expense.
The right-most column shows the net increase in value of moving to Miami for each of the householders. Bonnie achieves so much more value that her net value outweighs the rather significant hit in value that Donna experiences.
If the vote is by net value to the householders, they must vote to move. There are no householders that have a net zero change in value.

A decision based on net value does not account for the rather significant cost to Donna. If the household values mental health and interpersonal relationships, the fact that one member suffers badly from the move should be enough to sway the decision against it.
