Benny is thinking about going to the gym class and his benefit from going to the gym class is $482.

The gym class costs $258 and he will have to cancel his part-time job as a cleaner that pays $343.

Normally, he would be unwilling to do the part-time job for less than $Y. (Benny views the unpleasantness of the part-time job as an offset against its salary.)

Benny will decide to go to the gym class if and only if Y is at least[Answer].
