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) = 10x - 35, where x is the number of doors she knocks on during the week and E(x) is her earnings for the week in dollars.

What does the slope of Jessica's function represent?

Answer 1

A. For each additional door she knocks on, her earnings will increase by $10.
B. For each additional set of books she sells, her earnings will increase by $35.
C. For each additional set of books she sells, her earnings will increase by $10.
D. For each additional door she knocks on, her earnings will increase by $35.

Answer 2

Lol, do you go to CAVA?

Answer 3

no haha

Answer 4

I would say the answer is C, because 35 represents the expenses, and A says each door she knocks on, which would mean each door she knocks she sells a book. So C is the logical answer, I did the same problem a couple days for my school lol.

Answer 5

oh okay haha let me see if it works :o

Answer 6

Answer 7
