Alternative-Fuel Vehicles. The sales of alternative-fuel vehicles have more than tripled since 1995 (Source: Energy Information Administration). The exponential function $$ A(x)=246,855(1.0931)^{x} $$ where $x$ is the number of years after $1995,$ can be used to estimate the number of alternative-fuel vehicles sold in a given year. Find the number of alternative-fuel vehicles sold in 2000 and in 2013 . Then project the number of alternative-fuel vehicles sold in 2018 (IMAGE CANT COPY)

Carbon Dating. In $1970,$ Amos Flora of Flora, Indiana, discovered teeth and jawbones while dredging a creek. Scientists discovered that the bones were from a mastodon and had lost $77.2 \%$ of their carbon- 14 How old were the bones at the time they were discovered?
