Mrs. Jones is a woman of modest income. Give three pieces of evidence from the text that show the $10 she gives Roger is actually quite a sacrifice.

Mrs. Jones is obviously not a rich woman, so $10 would be worth a lot to her. Though the writer does not detail the part of town she lives in, he does say that she resides in a studio apartment with other "roomers."
There is also a suggestion that she relates not only to the boy's poverty but to his want for things he can't afford. As she tells him, “I were young once and I wanted things I could not get.” From this perspective, she shows no shock or false sympathy when the boy tells her that he has no one to care for him, suggesting that for her, such a situation is just a part of life. This is backed up by the empathetic way she converses with him at the dinner table. She seems to know exactly how to make him feel comfortable.

The woman did not ask the boy anything about where he lived, or his folks, or anything else that would embarrass him. Instead, as they ate, she told him about her job in a hotel beauty-shop that stayed open late, what the work was like, and how all kinds of women came in and out, blondes, red-heads, and Spanish. Then she cut him a half of her ten-cent cake.
