Answer: Option C. $13.90

Solution:

Approximate cost to go on a safari ($): y

Number of years since it opened in 2005: x

y=3.648*1.182^x

Cost in year 2013: y=?

Year 2013→x=2013-2005→x=8

y=3.648*1.182^8

y=3.648*3.810130162

y=13.89935483

y=13.90

The best estimate for the cost of a vehicle to drive through the safari in 2013 is $13.90
