Question

drew is selling books during the summer to earn money for college. he earns a commission on each sale but has to pay for heis own expenses. After a month of driving from neighborhood to neighborhood and walking door to door he figures out that his weekly earnings are approximately a linear function of the number of the doors he knocks on. he writes the equation of the function like this E(x)=20x-50 where x is the number of doors he knocks on during the week and E(x) is his earnings for the week in dollars. which of the following are reasonable interpretations of the yintercept of drew function

Answer 1

list all that apply
A. he can earn $20 per weeks even if he does not knock on any doors
B. his expenses are $50 per week
C. If he does not knock on any doors at all during the week, she will lose $50.
D. he will lose $20 per weeks if he does not knock on any doors

Answer 2

Well, A seems useless because without an original knock, there is no money, and D does not make sense, so that leaves two options.

Answer 3

so would it be C?

Answer 4

Well, the question says "list all that apply" so I would say both B and C, yes.
