<PRE><B>Question 659928</B>
Work backward
(12 left over + 2 dozen to neighbor) remaining amount
2(12 + 2(12)) amount before settin aside half for party
8 + 2(12 + 2(12)) includes the 8 the brothers ate
8+2(12+2(12) =
8 + 2(12+24)
8 + 2(36)
8 + 72
80
Since she double the recipe, 80/2 = 40 in one recipe

Proof
40 x 2 = 80
80 - 8 = 72
72/2 = 36
36-24 = 12
