The formula we need is this one: 
. Filling in accordingly, we have x+4(x+4+1)=x+1(x+1+11). Simplifying that we get (x+4)(x+5)=(x+1)(x+12). We will FOIL both sides to get 
. Combining like terms gives us this simplification: 0=4x-8. If we factor out the common 4, we have 0 = 4(x-2). By the Zero Product Property, eitheer 4=0 or x-2=0. Well obviously, 4 does not equal zero, so x-2 = 0, and x = 2.

Answer:
The required amount is $94.23.
Step-by-step explanation:
It is given that Nolan began a savings account three years ago and the value of his account after x years is
Anias started an account today and the value of her account is
We have to find the amount of money that would she have had to invest to have the same amount of money she has now.
Let the required amount be P.
If Anias started saving x amount in the savings account three years ago, then today the value of her account is
The current value is 100.
Divide both sides by 0.0612.
Therefore the required amount is $94.23.
