55. The table shows the price per capita
consumption C (in pounds) of broccoli in the
US. Create a scatter plot.
F 200
Year Consumption
1999 6.2
2000 5.9
2001 5.4
2002 5.3
2003 5.7
57. A cubic model for the broccoli problem
is C = 0.0583t3
– 1.796t2
+ 17.99t –
52.7
Graph this with the scatter plot. Is it a
good fit? Explain.
F 300
