What is the third quartile of this data set?
20, 21, 24, 25, 28, 29, 35, 37, 39, 42, 44

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

let's try to divide.

7 ÷ 0.8 = 8.75

there are three prime numbers with only 1 and themselves as factors so i say one is the greatest common factor for all of them.
