600x = 360000
So, the x should mean 'times'.
600 x 600 = 360000.
x = 600.
I am using the laws:
1)
2)
3)
an x is a base - the law is valid if the bases are the same number!
The solution in attachment :)
Answer:
part A you have correct.
is there a 'D" for part B? A through C answers don't seem correct.
after a response from the poster, "D" was the correct answer.
re-posting it because some random person deleted it.
<h3>Y
ou have the correct answer</h3><h3>Interest rate = 21.5%</h3>
===============================================
Work Shown:
i = P*r*t .... simple interest formula
i = simple interest
i = 2075-1000 = 1075
P = 1000 = amount borrowed (principal)
r = unknown interest rate
t = 5 = time in years
So,
i = P*r*t
1075 = 1000*r*5
1075 = 5000r
5000r = 1075
r = 1075/5000
r = 0.215
r = 21.5%
