I^32 = (i^4)^8 and i^4 = 1
so (i^4)^8 =1^8 = 1
The trick on all questions like this is to get as many i^4’s out of the way, since they’re all just 1s.
Answer:A
Step-by-step explanation:
Answer:
C. 6%
Step-by-step explanation:
You have to multiply 36 by A,B,C,D. Then add that number to 36.
First multiply all the options by the original price ($36)
A. 2.16% = 36 x 2.16% = 0.7776....this answer plus our original answer isn’t 38.16
B. 9.4% = 36 x 9.4% = 3.384....This answer plus 36 doesn’t equal 38.16
C. 6% = 36 x 6% = 2.16....2.16 plus 36 equals 38.16
D. 8% = 36 x 8% = 2.88....doesn’t equal 38.16 when added to 36.
Therefore 6% or C is the correct answer.
