Algebra I

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

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