What question does Ian ask in his letter at the end of the chapter?

In the context of $Just Mercy, Ian's question about how many photos he can buy with a dollar reflects a significant aspect of his life as an inmate—highlighting the limited means and the commercialization of small pleasures in prison. This particular inquiry speaks to the broader theme of how individuals are affected by their incarceration, focusing on the small yet meaningful connections that can be made through photographs.

This question also illustrates the emotional and psychological needs of incarcerated individuals, showcasing their desire to maintain some semblance of normalcy and personal connections with the outside world. In this environment, even the act of buying photographs becomes a poignant reminder of the value placed on personal memories and relationships, which are often stripped away in prison.
