Answer 1

Answer:

1000

Step-by-step explanation:

Answer 2

Answer:

$\boxed{1000}$

Step-by-step explanation:

The formula for the amount accrued [ƒ(x)] on an investment earning compound interest is

$f(t) = P(1 + r)^{t}$

where

P = the amount of money invested (the principal)

r = the interest rate per payment period expressed as a decimal fraction

t = the number of periods

Your formula is

$f(x) = 1000(1 + 0.05)^{x}\\\text{By comparison, we see that the term that represents the amount of money}\\\text{originally invested is \boxed{\textbf{1000}} }$
