Step-by-step explanation:

<em>Since, </em>

<u><em>Given that:</em></u>

<em>Laila made 12 Muffins</em>

<em>Shannon made 10 Muffins</em>

<u><em>Question to Answer:</em></u><em>
How many more did Laila make?</em>

<u><em>Solve:</em></u>

<em>Since it asking how many more laila made that means we have to subtract to find how many more laila has.</em>

<em>As given, we know that Laila made 12 Muffins and Shannon made 10 Muffins then:</em>

<em>Laila Muffins - Shannon Muffins</em>

<em>Which also means:</em>

<em>12 - 10</em>

<em>Which,</em>

<em>12 - 10 = 2</em>

<em>Hence, Laila makes 2 more Muffins than Shannon</em>
