The prompt
An Australian maker of home electric-vehicle (EV) chargers asks: in five years, how many home chargers will be sold in Australia each year, and what will that be worth? Use the household table below. A charger costs the household about AUD 1,800 installed.
Interviewer-led: the interviewer gives the household table, answers your clarifying questions with the ownership assumptions, and asks for the estimate step by step.
