Simple Interest Rate Formula: $\displaystyle A = P(1 + r)^t$

P is principle amount
r is rate
t is time

Step-by-step explanation:

Step 1: Define

Identify variables

P = 9500

r = 4.5% = 0.045

t = 5

Step 2: Find A

Substitute in variables [Simple Interest Rate Formula]: A = 9500(1 + 0.045)⁵
(Parenthesis) Add: A = 9500(1.045)⁵
Evaluate exponents: A = 9500(1.24618)
Multiply: A = 11838.7
