Simple Interest Rate Formula: [tex]\displaystyle A = P(1 + rt)[/tex]
- P is principle amount
- r is rate
- t is time
Step-by-step explanation:
Step 1: Define
Identify variables
P = 100
r = 4% = 0.04
t = 10
Step 2: Find Interest
- 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
