Natural log format in multiple regression practice problems 2021

hi, in the multiple regression practice problems if we need to take some of the independent variables as ln (natural logarithm) and in the problem itsel;f it is $100 million (PP 3. p340 of current 2021 curricullum) they take it as ln(100). In the next problem , however when it says C$900 million they take ln(900,000) - why is that?

Sloppiness, or stupidity.

you made me check errata, but it is not corrected there. so which one we shall use ?

For the slope coefficients, it makes no difference; you’ll get the same slopes either way.

The only difference will be in the intercept term.

In short, do it whichever way you prefer.
