To find the median price, we need to arrange the prices in ascending order:
$34.00, $35.00, $35.00, $35.00, $36.00, $36.00, $38.00, $39.00
The median is the middle value in a set of numbers. In this case, there are 8 prices, so the middle two prices need to be averaged to find the median.
The middle two prices are $35.00 and $36.00. To find the average, we add them together and divide by 2:
($35.00 + $36.00) / 2 = $71.00 / 2 = $35.50
Therefore, the median price of the collectibles sold by Hayley is $35.50.
