Answer
The solution to the formula for \(t\) is \(t=(S-P)/Pr\). Yes, this formula describes simple interest.
1Step 1 - Isolate the terms with \(t\) on one side
Subtract \(P\) from both sides of the equation. So we will have \(S-P=Prt\).
2Step 2 - Isolate the variable \(t\)
Divide both sides of the equation by \(Pr\). This gives us \(t=(S-P)/Pr\).
