There is a set of numbers: 24, 17, 7, 21, 8, 10, 22, 14, 9, 8. Find the interquartile range.

answer: it is 8

step-by-step explanation:

you know why its 8

b is the right answer

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)

the answer will be 80.
