(11 - 9i) - (15 - 12i) Ok so first multiple the subtraction sign into the parenthesis on the right had side of it.
And you get -15 + 12i
So now you have 11 - 9i -15 + 12i Combine Like terms
-9i + 12i = 3i
11 - 15 = -4
So your answer is 3i - 4
Hope you find this to your liking

Option C, 36, because it is the LCM (Least common multiple)
Tina made a down payment of $1,200 and her monthly payment amount is $200 for 36 months. So we will multiply $200 by 36 and add it to $1,200: $1,200 + 36 * $200 = $1,200 + $7,200 = $8,400. Finally we will add the residual value: $8,400 + $8,500 = $16,900. Answer: C. $16,900
