Deb’s boss gave her two tickets to the 49ers game because Deb met her sales quota. Deb’s boss purchased the tickets 2 months ago for $200 each. On the date Deb received the tickets, similar tickets were selling on StubHub for $150 each. On the date of the game, tickets were selling for $450 each because the week before the game, Aaron Rodgers was traded to the 49ers and he was scheduled to play in the game. Deb and her friend attended the game. What is Deb’s gross income, if any, from the receipt of the two tickets?
