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

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

Step-by-step explanation:

Step 1: Define

P = 7200

r = 0.75% = 0.0075

t = 5

Step 2: Solve for A

Substitute in variables [Simple Interest Rate Formula]: $\displaystyle A = 7200(1 + 0.0075)^5$
(Parenthesis) Add: $\displaystyle A = 7200(1.0075)^5$
Evaluate exponents: $\displaystyle A = 7200(1.03807)$
Multiply: $\displaystyle A = 7474.08$
