Not sure where I've gone wrong....

So as the title says I don't know what I've done. In the attached picture the question I am referring to is b and it has my workings. The answers says I should've done average age = .09 x log(20,000)=27.2 rounded. Where the heck did .09 come from??

Just did the question. Your working should be correct. Must've been an error.

I actually have no idea what I'm saying or talking about.

Maybe they were using a weird method that we can't comprehend
it should just be 2.39+5.89*log10(20000) :/
