What fraction of the sweaters cost $50 or less?

1/2
Step-by-step explanation:
The median is half way point, and $50 is at the median.
Also, this box plot is slipt into quarters. Two of the quarters added together gives us a 1/2.
(1/4 + 1/4 = 2/4 or 1/2)
Since, $35 to $45 is 1/4 and $45 to $50 is another 1/4 we added them together because we're after the cost of $50 and less than $50 at the same time.
Hope this helps!
