Step 8 Format Price with LiveData transformation

When using lifecycle implementation version 2.6.1 the transformations function can no longer be used and you must instead use example.map or example.switchMap rather than Transformations.map

Which version of the androidx.lifecycle library are you using? If it's 2.6.0 or newer then you should replace Transformations.map(_price) { } with _price.map { }. See the changelog for version 2.6.0.
