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

  • P is principle amount
  • r is rate
  • t is time

Step-by-step explanation:

Step 1: Define

Identify

P = 80

r = 2% = 0.02

t = 5

Step 2: Find Interest

  1. Substitute in variables [Simple Interest Rate Formula]:                                 A = 80(1 + 0.02 · 5)
  2. (Parenthesis) Multiply:                                                                                      A = 80(1 + 0.1)
  3. (Parenthesis) Add:                                                                                            A = 80(1.1)
  4. Multiply:                                                                                                             A = 88
