The given equation is as following:
[tex]y = 3.648*1.182^x[/tex]
x ⇒ The number of years since it opened in 2003.
To find the cost of a vehicle to drive through the safari in 2008
∴ x = 2008 - 2003 = 5
∴ [tex]y = 3.648*1.182^5=3.648*2.3072=8.4167[/tex]
∴ The best estimate for the cost of a vehicle to drive through the safari in 2008 ≈ $8.42
So, the solution is option C. $8.42
