Alright, we're in the home stretch here :) All you need to remember is that i² = -1. Otherwise, it is the same as FOIL
(3-2i)(1+7i)
3-2i+21i-14i² ← Replace the i² with -1, then simplify like numbers
3+19i+14
17+19i or C
Divide 22 by 2 sevenths; 22 / (2/7) = 77
24:28
52 (total books) minus 24 (fiction books) equals 28 (non fiction books)
