Table 1 Consider a small town with only three families, the Jones family, the Harris family, and the Wong 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. The Jones Family Number of Streetlights 1 2345 5 6 a. 1 streetlight b. 2 streetlights c. 3 streetlights d. 4 streetlights $180 140 90 30 0 a. 1 streetlight b. 2 streetlights The Harris Family Refer to Table 1. Suppose the cost to install each streetlight is $400. How many streetlights should the town install to maximize total surplus from the streetlights? c. 3 streetlights d. 4 streetlights $250 200 140 70 35 0 The Wong Family 5 $220 210 180 130 60 20 Refer to Table 1. Suppose the cost to install each streetlight is $400 and the families have agreed to split the cost of the streetlights equally. If the families vote to determine the number of streetlights to install, basing their decision solely on their own willingness to pay (and trying to maximize their own surplus), what is the greatest number of streetlights for which the majority of families would vote "yes?"
