<u>Algebra I</u>

Simple Interest Rate Formula: \displaystyle A = P(1 + r)^t

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

Step-by-step explanation:

<u>Step 1: Define</u>

P = 7200

r = 0.75% = 0.0075

t = 5

<u>Step 2: Solve for </u><em><u>A</u></em>

  1. Substitute in variables [Simple Interest Rate Formula]:                               \displaystyle A = 7200(1 + 0.0075)^5
  2. (Parenthesis) Add:                                                                                          \displaystyle A = 7200(1.0075)^5
  3. Evaluate exponents:                                                                                       \displaystyle A = 7200(1.03807)
  4. Multiply:                                                                                                           \displaystyle A = 7474.08
