Work Step by Step
$\mathrm{t}=0$, the year is 2005+0
$\mathrm{p}(0)=10.8$
The annual petrochemical production in Mexico in 2005 was 10.8 billion metric tons.
$\mathrm{t}=$2, the year is 2005+2
$\mathrm{p}(2)=11.8$
The annual petrochemical production in Mexico in 2007 was 11.8 billion metric tons.
$\mathrm{t}=4$, the year is 2005+$4$
$\mathrm{p}(4)=12.0$
The annual petrochemical production in Mexico in 2009 was $12.0$ billion metric tons.
