<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 (in years)

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>P</em> = 7300

<em>r</em> = 3% = 0.03

<em>t</em> = 10

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

  1. Substitute in variables [Simple Interest Rate Formula]:                                 \displaystyle A = 7300(1 + 0.03)^{10}
  2. (Parenthesis) Add:                                                                                            \displaystyle A = 7300(1.03)^{10}
  3. Evaluate exponents:                                                                                         \displaystyle A = 7300(1.34392)
  4. Multiply:                                                                                                              \displaystyle A = 9810.59
