• A is final amount
• P is principle amount
• r is rate
• n is compounded rate
• t is time

Step-by-step explanation:

Step 1: Define

Identify given variables.

P = $47,323.15

r = 0.05

n = 1

t = 3

Step 2: Find Interest

1. [Compounded Interest Rate Formula] Substitute in variables:
   $\displaystyle A = 47323.15 \bigg( 1 + \frac{0.05}{1} \bigg) ^{1(3)}$
2. Evaluate:
   $\displaystyle A = \boxed{54782.5}$

∴ Jack will gain $7,459.31 and have a net balance of $54,782.50.
