Base on first attachment:

There are 12 people ⇒ Emily, Delvenal, 10 other friends that was suppose to come

Either :

cut the pan of brownies into the 12 pieces

cut the pan of brownies into 24 pieces

But from this second attachment we know that:

Out of the 10 friend that war suppose to come only 7 came.

Thus if they cut the pan of brownies into 12 pieces then

Emily and delvenal + 7 friend = 10 people

12 - 10 = 2

Hence, 2 pieces of brownies are left.

Thus, if they cut the pan of brownies into 24 pieces then

Emily and delvenal + 7 friend = 10 people

24 - 10 = 14

Hence, 14 pieces of brownies are left.
