To represent the situation with an inequality, we will use the following variables:
- Let \( x \) be the number of batches of scones.
- Let \( y \) be the number of batches of miniature tarts.
Each batch of scones requires 2 eggs, so the total number of eggs used for \( x \) batches of scones is \( 2x \).
Each batch of miniature tarts requires 3 eggs, so the total number of eggs used for \( y \) batches of miniature tarts is \( 3y \).
Since Mrs. Hogan has up to 12 eggs, we can set up the inequality based on the total number of eggs used:
\[ 2x + 3y \leq 12 \]
This is the inequality in standard form that describes the situation.
