P is principle amount
r is rate
t is time (in years)

Step 1: Define

Identify variables

P = 7300

r = 3% = 0.03

t = 10

Substitute in variables [Simple Interest Rate Formula]: $\displaystyle A = 7300(1 + 0.03)^{10}$
(Parenthesis) Add: $\displaystyle A = 7300(1.03)^{10}$
Evaluate exponents: $\displaystyle A = 7300(1.34392)$
Multiply: $\displaystyle A = 9810.59$
