Answer
Brief Explanations:
The data shows that from 1979 - 2009, for women 25 years and older in the US, the percentage of a man's salary they earned increased. Among different age - groups, younger women (20 - 24 years old) already had a relatively high percentage (93%) and older women (45 - 54 years old) had a lower percentage (73.6%). But overall, for women 25 and older, the earning power increased. There is no information about women under 25. So we can infer that for women over 45, their earning power is increasing as part of the overall trend for women 25 and older.
Answer:
It is increasing for women over 45.
