Question

solve the simple interest formula, $i = prt$, for $t$.$t = ipr$$t = \frac{i}{pr}$$t = \frac{r}{ip}$$t = \frac{p}{ir}$

Explanation:

Step1: Isolate t via division

Divide both sides by $Pr$.
$$\frac{I}{Pr} = \frac{Prt}{Pr}$$

Step2: Simplify the equation

Cancel $Pr$ on the right side.
$$t = \frac{I}{Pr}$$

Answer:

$t = \frac{I}{Pr}$
