Current estimates put the formula for the price per pound of Freon at where t is the number of years since 1990. Find the price of Freon in 1990 and 1999. What is the anticipated cost for Freon in the year 2009?
A) $1.89 in 1990, $13.74 in 1999 and $131.15 in 2009
B) $1.89 in 1990, $13.14 in 1999 and $25.64 in 2009
C) $1.89 in 1990, $14.08 in 1999 and $131.15 in 2009
D) $1.89 in 1990, $21.26 in 1999 and $44.89 in 2009
E) $1.89 in 1990, $14.08 in 1999, and $130.63 in 2009
