Sherlock wants to rent a textbook. he has to pay a fixed base cost plus a daily rate for renting the textbook. the table shows the amount of money, y, in dollars, that sherlock has to pay for renting the textbook for x days

answer options:
a) y = x + 13
b) y = 7x + 13
c) y = x + 6
d) y = 7x + 6

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
