First, we had to order the numbers from least to greatest to have this: $13.95,$19.99,$23.95,$24.59,$28.99,$29.98. Next, we had to locate the middle number to find the median, so for this we had two number which are $23.95 and $24.59. Then, we had to add two numbers together and divided them after, so we had the median equal $24.27. The first quartile is $19.99 and the third quartile is $28.99. Finall, to find to interquartile range we just need to subtract the third quartile with the first quartile to get the final result is 9. Hope you get it!
