Algebra I

Simple Interest Rate Formula: A = P(1 + rt)

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

Step-by-step explanation:

Step 1: Define

Principle amount P = 4700

Rate r = 2.15% = 0.0215

Time t = 3 years

Step 2: Solve for A

1. Substitute [SIRF]:                    A = 4700[1 + 0.0215(3)]
2. [Brackets] Multiply:                 A = 4700[1 + 0.0645]
3. [Brackets] Add:                       A = 4700[1.0645]
4. Multiply:                                   A = 5003.15

Step 3: Find Interest Gained

Final - net

1. Substitute:                    5003.15 - 4700
2. Subtract:                       303.15
