1) Consider a small town with only three families, the Greene family, the Brown family,
and the Black family. The town does not currently have any streetlights so it is very
dark at night. The three families are considering putting in streetlights on Main Street
and are trying to determine how many lights to install. The table below shows each
family's willingness to pay for each streetlight.
Suppose the cost to install each streetlight is $900 and the families have agreed to split

trying to maximize their own surplus), what is the greatest number of streetlights for
which the majority of families would vote "yes?"
a.1 streetlight
