CFAI EOC Reading 12 Mulitple Regression

CFAI EOC Reading 12 page 412: Can anyone explain why the solution has you taking LN of 900,000 here and using 1 as the decline rather than .01? I used LN 900 and .01 and got the wrong answer. Using 900,000 seems odd since the number is actually 900,000,000 so if anything I would think that you would use 900 and .01 or 900,000,000 and 1. Thanks in advance for the help
