Hard question! Jessica is selling books during the summer to earn money for college. She earns a commission on each sale but has to pay for her own expenses. After a month of driving from neighborhood to neighborhood and walking door-to-door, she figures out that her weekly earnings are approximately a linear function of the number of doors she knocks on. She writes the equation of the function like this: E (x) = 20x - 50, where x is the number of doors she knocks on during the week and E (x) is her earnings for the week in dollars. Which of the following are reasonable interpretations of the y-intercept of Jessica's function? Check all that apply.

A. Her expenses are $50 per week.

B. She can earn $20 per week even if she does not knock on any doors.

C. If she does not knock on any doors at all during the week, she will lose $50.

D. She will lose $20 per week if she does not knock on any doors.
