Final answer:
The question lacks the necessary details to provide an answer. It appears to be part of a mathematical word problem, but without additional information, we cannot perform the required calculations.
Step-by-step explanation:
The question "How much money did Anna's mom give her when she went away to college?" is missing specific information that would allow for a mathematical answer. Generally, such a question would appear in a mathematics context if it were part of a word problem requiring some calculation. For example, if the question stated that Anna's mom gave her a certain amount of money and then provided additional details about how Anna spent or saved that money, we could use mathematics to determine either the initial sum given or the remaining balance after various transactions. However, without such details or a clear context, we cannot accurately answer this question.
