Hi, can you please help me with this question?

Alice works 40 hours a week at her current job, getting paid $15 an hour and has a disutility of work of $5 an hour.Suppose that if she loses her current job, she gets unemployment benefits of $500 a week. This benefit is available only for the first 10 weeks of unemployment, after which she gets no benefit. If the expected duration of unemployment is 30 weeks, after which Alice can be employed for $15 an hour at another job, what is Alice's expected net benefit from keeping her current job?

a.

She expects to have a benefit of -$100 a week for the first 10 weeks.

b.

She expects to have a benefit of $8000 over the full 30 weeks.

c.

Her expected net benefit from working is negative, so she is better off quitting work and living off the government benefits.
