The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
Sales tax = 7.5%
7.5% of 12.50 = (7.5/100) * 12.5 = 0.075* 12.5 = 0.9375
tax = 0.9
Total pay = price + tax = 12.5 + 0.9375 = 13.4375
Total pay ≈ 13.44

the correct answer is 124
