Over her summer break, Kim had to read a total of fifteen books before school started again in the fall. She tracked her progress weekly and made the following graph.

Question

The graph titled Kim’s Reading shows number of books on y-axis and number of weeks on x-axis. Kim graphed the points (0, 0), (1, 1), (2, 3), (3, 5), (4, 7), (5, 8), (6, 9), (7, 9), (8, 11), (9, 14), and (10, 15).

According to the graph, about how many books did Kim read each week?

A.
23

B.
112

C.
212

D.
15

Answer 1

To determine about how many books Kim read each week, we can calculate the average number of books she read over the course of her summer break.

According to the data, Kim read a total of 15 books over a span of 10 weeks. To find the average, we can use the formula:

\[ \text{Average} = \frac{\text{Total number of books}}{\text{Total number of weeks}} = \frac{15}{10} = 1.5 \]

So, Kim read an average of 1.5 books each week.

Now, let's analyze the answer choices given:

A. 23
B. 112
C. 212
D. 15

None of the options provided match 1.5 books per week. The answer choices appear to be incorrect or unrelated to the context of the question. The closest related number in terms of total books read (which is 15) is option D, but it is important to note that this is not the average per week.

If you need a single answer among the choices, D (15) represents the total number of books read, but the average number of books per week Kim read is 1.5 books.
