Answer:
a
Step-by-step explanation:
By graph of object A the rate of change is estimated at 17/6.
Object B's rate of change is 10/3=20/6.
Comparing object A to object B:
17/6 <20/6
Object B is faster by:
17/6x=20/6
(6/17)(17/6)x=(20/6)(6/17)
x=20/17≈1.18
B)
Object B by a factor of 1.19
Since I made an estimation from graph of object A , my solution is off by. 01 but it is the closest I can get. The solution B is correct.
Given:
Book club A charges $20 for membership and $2 per book rental.
Book club B charges $10 for membership and $3 per book rental.
To find:
The number of books for which the cost be the same at both book clubs.
Solution:
Let x be the number of books.
Book club A charges $20 for membership and $2 per book rental. So, the total cost is
...(i)
Book club B charges $10 for membership and $3 per book rental. So, the total cost is
...(ii)
Equating (i) and (ii), we get



The total cost is



Therefore, the total cost at both book clubs are same for 10 rental books and that cost is $40.
