To represent the situation with an inequality, we need to consider that Shannon's total spending on decorations and food cannot exceed $175.
Let \( x \) be the amount Shannon spends on food. She spent $62.29 on decorations, so the total amount she spends on both decorations and food is \( 62.29 + x \).
The inequality that correctly represents the situation is that the total spending must be less than or equal to $175. Therefore, the correct inequality is:
\[ 62.29 + x \leq 175 \]
So, the correct response is:
B \( 62.29 + x \leq 175 \)
