Answer: 5i
Step-by-step explanation:
-25 = 5 x 5
i^2 = -1
5^2 ( -1 ) = -25
Below is the solution:
<span>A = 2000[1 + (.042/2)]^(2*2)
A = 2173.366476962
A = 2173.37
I = 2173.37 - 2000
I = 173.37
A = 2000[1 + (.036/12)]^(12*2)
A = 2149.0790382667085294501721261072
A = 2149.08
I = 2149.08 - 2000
I = 149.08
173.37 - 149.08 = 24.29</span>
