This problem might be clearer for you, as well as for others, if you'd please use the Equation Editor to write y = 85,000(0.95)x properly.  (0.95)x normally means "0.95 times x," which is not correct here.$$y = 85,000(0.95)x \rightarrow y=85000(0.95) ^{x}$$ is much clearer and less likely to be misinterpreted.

Now, please substitute 0 for x in the above formula.  What is the value of$$(0.95)^0?$$

Continue on to find the value of y when x=0.  Good luck!
