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

Answer 1

The answer is letter "D" y=7x + 6. To show that this answer is correct, we need to substitute each value of x and the solved y value should be correct.
For x=0
y=7(0)+6
y=6
For x=1
y=(1*7)+6
y=13
For x=2
y=(2*7)+6
y=20
For x=3
y=(3*7)+6
y=27 and same solution for x=4.

Answer 2

The correct answer would be y=7x + 6
