Using simple interest, it is found that Devin will pay $60,125 altogether.
The amount paid in <u>simple interest</u> is:
In which:
- P is the principal.
- r is the interest rate, as a decimal.
- t is the time, in years.
In this problem:
- Owes $26,000 in student loans, thus
- Interest rate of 8.75%, thus
- Paid off in 15 years, thus .
The amount he will pay is of:
Devin will pay $60,125 altogether.

<h3>How to prove a trigonometric equivalence by algebraic and trigonometric procedures</h3>
In this question we have <em>trigonometric</em> expression whose equivalence to another expression has to be proved by using <em>algebra</em> properties and <em>trigonometric</em> formulas, including the <em>fundamental trigonometric</em> formula, that is, cos² x + sin² x = 1. Now we present in detail all steps to prove the equivalence:
Given.
Subtraction between fractions with different denominator / (- 1) · a = - a.
Definitions of addition and subtraction / Fundamental trigonometric formula (cos² x + sin² x = 1)
Definition of tangent / Result
By using <em>algebra</em> properties and <em>trigonometric</em> formulas we conclude that the <em>trigonometric</em> expression is equal to the <em>trigonometric</em> expression . Hence, the former expression is equivalent to the latter one.
