105 maybe
Step-by-step explanation:
In order to solve a negative exponent, you have to consider the multiplicative inverse of the base:

So, if we solve the negative exponent on the left hand side, we have

which is the right hand side.
They are equivalent because they have the same numbers and when you do the math it give 96 for both of them
I think the answer is 30....Not sure
To determine the expected total value of the investment after 20 years, we simply plug in the given to the prepared equation,
A = P x (1.12^n)
Substituting the known values,
A = ($5000) x (1.12^20)
A = $48,231.47
Thus, the expected amount of your purchase is $48,231.47.
