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) = 10x - 30, 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?
choose all that apply.
a. her expenses are $30 per week.
b. if she does not knock on any doors at all during the week, she will lose $30.
c. she can earn $10 per week even if she does not knock any doors
d. she will lose $10 per week if she does not knock on any doors.
since the equation is subtracting 30,
you can assume that A her expenses are 30 per week
and B if she doesn't knock on any doors , she would still have the expenses, therefore losing $30
So both A & B apply
answer: ouch. thats difficult
honestly bro aint no one got time to answer these dumb question just do it p***y
