To find the percentage of books sold that were over $9.99, we need to sum the number of books sold in the price ranges that exceed $9.99 and then divide that sum by the total number of books sold (70,000), and finally multiply by 100 to get a percentage.
The relevant price ranges are:
- E: $10.00-$14.99
- F: $15.00-$24.99
- G: $25.00 or more
The respective quantities of books sold in these ranges are as follows:
- E: 14,000
- F: 15,000
- G: 9,000
Now we can calculate the total number of books sold in these ranges:
\[
14,000 + 15,000 + 9,000 = 38,000
\]
Next, we find the percentage of the total 70,000 books that this represents:
\[
\text{Percentage} = \left( \frac{38,000}{70,000} \right) \times 100
\]
Simplify the fraction:
\[
\frac{38,000}{70,000} = \frac{38}{70}
\]
Now divide 38 by 70:
\[
\frac{38}{70} \approx 0.542857
\]
Finally, multiply by 100 to convert to a percentage:
\[
0.542857 \times 100 \approx 54.29\%
\]
Therefore, approximately 54.29% of the 70,000 books sold were over $9.99.
