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
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.
