Professor Brooke works at City University. Recently, to get faculty to answer emails and phone calls from students over the weekend, City University purchased cell phones for all professors. The University pays $1,000 a year for the phones, and has determined that professors will use them 50% of the time for personal purposes.

Question 7 options: a) $0. b) $200. c) $500. d) $700
