Jason : 8,8,11,13,14,14,15,18,21,22,22,27,27,28,30

median = 18

IQR = 27 - 13 = 14

Ed : 7,12,12,15,19,21,21,21,21,22,23,23,26,27,27

median = 21

IQR = 23 - 15 = 8

Their medians cannot be compared based on their IQR's are 6 points apart

$10+5x=24+3x$

Solve for x

$5x-3x=24-10$

$2x=14$

$x=\$7$
