Let w be the unknown number of weeks. The total amount that Justin saves is the product of the amount he saves every week and the number of weeks. That is,

Rearranging the equation for w,
w = $133 / $9.50
Thus, the answer is 14.

Put numbers in order: 4,5,6,6,7,8,9,9,10,10,12,12,14,15
Cut the list into two equal parts: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Find middle numbers: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Lower quartile: 6
Upper quartile: 12
The difference of the values of the first and third quartiles of the data set is 12 - 6 = 6
