Answer:
It looks like ur doing complex conjugates sooooo the answer is 21 - 12i
They way you show work is
(3-4i)(1+5i) - (2-i) <—— use foil method on first 2 parentheses
= 3 + 11i - 20i ^2 - 2 + i ( remember i^2 = -1)
= 3 + 11i + 20 -2 + i
= 21 + 12i
So the cost of 12 pencils is 2.04 dollars. If you want to find 1/12 of the amount, divide 2.04 by twelve.
2.04/12= 0.17
One pencil costs $0.17. The answer is B.
