Enrollment at a community college over the last 4 years is: 1,800 (year 1), 2,300 (year 2), 3,000 (year 3), and 3,700 (year 4). Show the data on a bar graph. Let each horizontal increment represent 500 students.
Your boss would like your help on a marketing research project she is conducting on the relationship between the price of soda and the quantity of
soda demanded. She hands you the following document:
Price of Soda
Quantity of Soda Demanded
(Dollars per can)
(Billions of cans)
0.50
2,000
0.75
1,500
1.00
1,000

Your task is to take this
and construct a graphical representation of the data. In doing so, you determine that as
the price of soda rises, the quantity of soda demanded decreases. This confirms the
