I would guess that it is about $30 from ABQ to the Tram.

The closest approach leaves you with about a 3.5 mile walk.

Surprisingly, there is a route up Unser that takes you by Petroglyph park (Rincenada Canyon), and the Visitor center, but a car is better.
Petroglyph National Monument (U.S. National Park Service)
For the price of a one-day rental, you can pay for the taxi from Petroglyph Monument to the Tram and back to Old Town or wherever you are staying.
You have the additional benefit of not having to wait for the taxi to be dispatched and are not tied to the bus schedule.
However, we don't know the specifics of TravillionRex's situation. Perhaps they cannot drive a car or are too young to rent a car. So maybe a bus to the Monument and a taxi to the Tram will work just fine.
