Number 19 I think is if you add the awnser to one of the numbers you where subtracting and you get the other number you where subtracting you are right like...

Lets say you had the problem 3-2 which is obviously 1 but if you did 2+1 it's 3 so that's how you check.

Nolan begins a savings account with $100 at 2% interest according to the equation where Vn is the value of his account after x y

Anna71 [15]

Let's assume

amount invested is P

Since, we are given

Nolan invested equation as

$V_n=P(1.02)^x$

Anias invested equation as

$V_a=100(1.02)^{x-3}$

now, we can set them equal

$P(1.02)^x=100(1.02)^{x-3}$

now, we can solve for P

$P=\frac{100(1.02)^{x-3}}{(1.02)^x}$

now, we can simplify it

$P=100(1.02)^{x-3-x}$

$P=100(1.02)^{-3}$

$P=94.2322$

So, she needed to invest $94.2322 to have the same amount of money that she has three years later........Answer
