This is a statistic question in a college course. Thanks
Variable = amount of money spent on books
N = 300
Minimum = 25.0
Q1 = 118.8

Q3 = 261.3
Maximum = 400.0
Approximately how many people spent more than $118.80 on books?

  225

Step-by-step explanation:

$118.80 is the first quartile, so 25% of the people spent that amount or less. So, the number spending $118.50 or more is 3/4 of the total number:

  (3/4)·300 = 225

About 225 people spent more than $118.80 on books.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
