Question 1001191: 8.) according to the EPA, we sent 251 million tons of garbage to landfills in 2012, and a function for future landfill use is: y=251(0.943)t that gives the millions of tons of garbage at t years after 2012
A.) interpret this by determining if the landfill use is growing or decaying, and the rate of growth/decay.
B.) use the function to estimate the amount of garbage that will go to landfills in 2015

Examine y=251%280.943%29%5Et
Since the base .943 is less than one, the function is decreasing and so is landfill usage (supposedly).
In 2015, t=3, so that
y=251%280.943%29%5E3 =
210.48 million tons of garbage
