Simple Interest Rate Formula:
- <em>P</em> is principle amount
- <em>r</em> is rate
- <em>t</em> is time
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>P</em> = 100
<em>r</em> = 4% = 0.04
<em>t</em> = 10
<u>Step 2: Find Interest</u>
- Substitute in variables [Simple Interest Rate Formula]: A = 100(1 + 0.04 · 10)
- (Parenthesis) Multiply: A = 100(1 + 0.4)
- (Parenthesis) Add: A = 100(1.4)
- Multiply: A = 140
