To represent the situation where Anna Maria does not want to spend more than $500, we need to consider her expenses.
She plans to spend $325 on travel and camping, and she budgets $20 for each meal. If we let \( m \) represent the number of meals, her total spending can be modeled as:
\[ 325 + 20m \]
Since she doesn't want to spend more than $500, we set up the inequality:
\[ 325 + 20m \leq 500 \]
Thus, the correct inequality is:
325 + 20m ≤ 500
