the results of an analysis, on the makeup of garbage, done by the Environmental Protection Agency was published in 1990. Some of the results are given in the following table, which for various years gives the number of pounds per person per day of various types of waste materials.
Waste Materials 1960 1970 1980 1988
Glass 0.20 0.34 0.36 0.28
Plastics 0.01 0.08 0.19 0.32
Metals 0.32 0.38 0.35 0.34
Paper 0.91 1.19 1.32 1.60
For plastics, calculate the average rates of change between consecutive data points in the table. Interpret the meaning of your results.
a. The rate of increasing from each decade to the next.
b. The rate of increase decreases from each decade to the next.
c. The rate of increase increases during the 1970's, but then decreases during the 1980's.
