How to approach this case
A market sizing is solved by stating your formula before writing down a single number. Pick a starting point you can estimate (a population, an installed base, a number of outlets), split it into segments that behave differently, then apply a frequency and a price to each. Say your assumptions out loud and round to keep the arithmetic simple. The interviewer grades the reasoning and the final sanity check of the order of magnitude far more than the result itself.
This case involves calculations: talk through your arithmetic out loud, round when it is reasonable and state the order of magnitude you expect before the exact result. It also includes a chart or table to read: first say what the axes show, then give the main message in one sentence before going into detail.
