Gina and Liz have been friends their whole lives. Gina is two years older than Liz and has been working at a job for two years. After Liz graduates from high school they decide to take a trip driving across the United States. Liz saves $800 from a part-time job. Gina has about $5,000 in savings. When Gina and Liz get back from their 3-week trip, they are very unhappy with each other. Gina is unhappy because she ended up spending more money than Liz did. Gina feels that Liz did not pay her fair share. Liz had understood that Gina was volunteering to buy extras for them because Gina had more money. She did not think that Gina had expected to be reimbursed for these extra charges, such as staying at nicer hotels with swimming pools and going out to fancy restaurants once in a while. In the end, Gina spent $1,500 and Liz spent $800. However, they did not keep good records of who spent what, although the gas and car expenses were shared equally. They go to mediation because they want to work out their problems. 4. List at least 4 possible solutions to this dispute
