Q= X/100 of $1.37 = 0.35
1.37x/100 = 0.35
1.37x = 35 then divide each side by 1.37
Result is 25.5474453 percent, round up to nearest tenth.
Answer is 25%

Not a right-angle triangle

Considering the given box-and-whisker plot, it is found that the bookstore sold between 2 to 12 books in 20 days.
<h3>What does a box-and-whisker plot shows?</h3>
A box and whisker plot shows three things:
- The 25th percentile, which is the median of the bottom 50%.
- The median, which splits the entire data-set into two halfs, the bottom 50% and the upper 50%.
- The 75th percentile, which is the median of the upper 50%.
From the plot given in this problem, the have that:
- The 25th percentile is of 2.
- The 75th percentile is of 12.
This means that the percentage of days in which between 2 to 12 books were sold is:
P = 75 - 25 = 50%.
Hence, out of 40 days, the amount of days is:
0.5 x 40 = 20 days.
