Simple Interest Rate Formula: A = P(1 + rt)
- <em>P</em> is principle amount
- <em>r</em> is rate
- <em>t</em> is time (in years)
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>P</em> = 5000
<em>r</em> = 6.5% = 0.065
<em>t</em> = 5
<u>Step 2: Find Interest</u>
- Substitute in variables [Simple Interest Rate Formula]: A = 5000(1 + 0.065 · 5)
- (Parenthesis) Multiply: A = 5000(1 + 0.325)
- (Parenthesis) Add: A = 5000(1.325)
- Multiply: A = 6625
