Hi, you've asked an incomplete question. The remaining part of the question reads;

the first paragraph;

I spent my teens and much of my twenties collecting printed rejections. Early on, my mother lost $61.20—a reading fee charged by a so-called agent to look at one of my unpublished stories. No one had told us that agents weren’t supposed to get any money upfront, weren’t supposed to be paid until they sold your work. Then they were to take ten percent of whatever the work earned. Ignorance is expensive. That $61.20 was more money back then than my mother paid for a month’s rent.

The last sentence of the first paragraph (“That . . . month’s rent”) primarily serves to

Explanation:

By saying, "That $61.20 was more money back then than my mother paid for a month’s rent" the narrator had revealed a very interesting statistic about the value of money back then.

In other words, the context surrounding the statement helps the average reader quickly understand that a month's rent used to be lesser than $61.20; very interesting statistics at that.
