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

Assuming the following data
X: 44, 44, 11, 11, 55
Y: 66, 55, -1, -3, 88
We want to find a linear model
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
