  • Left to Right  <u> </u>

<u>Algebra I</u>

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

  • <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> = 9500

<em>r</em> = 4.5% = 0.045

<em>t</em> = 5

<u>Step 2: Find </u><em><u>A</u></em>

  1. Substitute in variables [Simple Interest Rate Formula]:                                 A = 9500(1 + 0.045)⁵
  2. (Parenthesis) Add:                                                                                            A = 9500(1.045)⁵
  3. Evaluate exponents:                                                                                         A = 9500(1.24618)
  4. Multiply:                                                                                                             A = 11838.7
