the formula for simple interest is i = prt, where i is the interest earned, p is the principal, r is the interest rate and t is the number of years. solve the formula for r in terms of p, i and t.

the formula for simple interest is i = prt, where i is the interest earned, p is the principal, r is the interest rate and t is the number of years. solve the formula for r in terms of p, i and t.

Answer

Explanation:

Step1: Isolate $r$ term

Given $I = Prt$, divide both sides by $Pt$. $\frac{I}{Pt}=\frac{Prt}{Pt}$

Step2: Simplify the right - hand side

$\frac{I}{Pt}=r$

Answer:

$r=\frac{I}{Pt}$
