1/8 * 2/5 = 2/40 reduces to 1/20 are tubas
1/20 * 240 = 240/20 = 12 are tubas
Okay. So, the amount was previously $5 per 1,000. The price has gone up to $5.90. That’s a 90 cent change from the previous 5 dollars. To find the percent of change, we have to do change/original. 0.90/5 is 0.18. Multiply that by 100 to get 18. The percent increase to the nearest whole number is 18%.

1. First of all arrange the data set in either ascending or descending order.
12, 19, 24, 26, 31, 38, 53. N = 7 (number of data items)
Median position = 1/2(N + 1)th item = 1/2(7 + 1)th item = 1/2(8)th item = 4th item = 26
First quatile = 1/4(N + 1)th item = 1/4(7 + 1)th item = 1/4(8)th item = 2nd item = 19
Third quatile = 3/4(N + 1)th item = 3/4(7 + 1)th item = 3/4(8)th item = 6th item = 38
Interquatile range = Third quartile - first quatile = 38 - 19 = 19
