Shannon works for a small company that sells books online and is responsible for mailing out the books to customers. Every morning she gets in line at the local post office and estimates the length of her wait. The length of her wait depends on the number of people in line ahead of her.
w = the length of time Shannon will need to wait
p = the number of people in line ahead of Shannon
Which of the variables is independent and which of the variables is dependent?
p is the independent variable and w is the dependent variable
