Solution: The regression equation is:
[tex]y=3.648 \times 1.182^{x}[/tex]
Where x is the number of years since it opened in 2003.
We have to find the cost of a vehicle to drive through the safari in 2008.
[tex]\therefore x= 2008 - 2003=5[/tex]
Therefore using the given equation, we have:
[tex]y=3.648 \times 1.182^{5}[/tex]
[tex]=3.648 \times 2.3072[/tex]
[tex]=8.42[/tex]
Therefore, the best estimate for the cost of a vehicle to drive through the safari in 2008 is $8.42.
Hence the option C.$8.42 is correct
