According to a 2010 survey of British students
(www.leedsuniversityunion.org.uk/helpandadvice/ money/costofliving), a typical student had a budget of £18.8 per week to spend on mobile telephones, Internet access, and music. That student spent about 45% on phones, 28% on Internet access, and 27% on music. Estimate the student's Cobb-Douglas utility function for these three goods?
