Step-by-step explanation:
Given
and
(say).
Then,

From the above 3 equations,

From the equations, we get

Since
, the negative value is rejected.

The answer is E.
First you need to find the rate. You must divide 1.8 by 100
1.8/100 = .018
Then add 1.
.018 + 1 = 1.018
Then times the starting amount with 1.018. The starting amount 750
750(1.018) = <span>763.5.
</span>As you can see, in option E that is the 2nd number.
Now we must find the next number.
You will do 750(1.018)^x
x represents the time.
763.5 was the first month.
750(1.018)^2 is the 2nd month.
750(1.018)^2 = <span>777.244 which is the 3rd number in option E</span>
