<em>From the first attachment or we can also say:</em>
<em>brainly.com/question/27391854</em>
<em>Base on first attachment: </em>
<em>There are 12 people ⇒ Emily, Delvenal, 10 other friends that was suppose to come</em>
<em>Either :</em>
<em>cut the pan of brownies into the 12 pieces</em>
<em>cut the pan of brownies into 24 pieces</em>
<em>But from this second attachment we know that:</em>
<em>Out of the 10 friend that war suppose to come only 7 came.</em>
<em />
<em>Thus if they cut the pan of brownies into 12 pieces then</em>
<em>Emily and delvenal + 7 friend = 10 people</em>
<em>12 - 10 = 2</em>
<u><em>Hence, 2 pieces of brownies are left.</em></u>
<em />
<em>Thus, if they cut the pan of brownies into 24 pieces then</em>
<em>Emily and delvenal + 7 friend = 10 people</em>
<em>24 - 10 = 14 </em>
<u><em>Hence, 14 pieces of brownies are left.</em></u>
