Question

The formula for simple interest is I = Prt where I is the interest earned, P is the Principal, r is the interest, and t is the number of years. Solve the formula for "t" in terms of P, i, and r. t = ?

Answer 1

`I=Prt\text{ }`

To solve "t", simply divide both sides by Pr.

`\begin{gathered} (I)/(Pr)=\frac{Prt\text{ }}{Pr} \\ (I)/(Pr)=t \\ t=(I)/(Pr) \end{gathered}`

Therefore, the formula for t is t = I/Pr as shown above.
