An environmental protection group had its members sign a pledge to try to reduce the amount of garbage they throw out by 3% each year. On the year that the pledge was
signed, each person threw out an average of 1,800 pounds of garbage. Which
exponential function could be used to model the average amount of garbage each year
after signing the pledge?
a. y = 0.97 X 1,8000
b. y = 1,800 X 40.97
c. y = 1,800 x 1.970
d. y = 1,800 x 0.970
