Answer: The Answer choice to this question is A) 12,330
Explanation:
If we assume that the relationship is exponential, then the values of Cash Paying Drivers have a Constant ratio.
->
is approximately constant as
-> 0.9728, 0.9540, 0.9567, 0.9298
The mean of the value above is 0.9533
After 9 weeks, the best estimate of the number of drivers who pay by Cash will be 18,428 x (0.9533)^8 ≈ 12,569
Since this is closer to 12,330, so the answer is A
