Question

8.

John is thinking about watching a football game with his friend. John is willing to pay HK$150 for

watching the game. A ticket of the game costs HK$73 and he will have to cancel his part time job that

pays HK$285. Normally, he would be unwilling to do the part time job for less than HK$Y. (John

views the unpleasantness of the part time job as an offset against its salary.) John will decide to watch

the game if Y is at most [ Answer08 ].

Answer 1

8.

y = monetary equivalent to the unpleasantness of job

so we can say equivalent cost = (cost of ticket) + (salary of part time job) - (monetary equivalent to the unpleasantness of job)

= 73 + 285 - y

150 = 73 + 285 - y

y = 208
