Question

Got cut off while saying thanks to last tutorial t bg at helped me.

Answer 1

We are given the following equation.

`A=p+prt`

we are asked to find an equation for "t". To do that, we are going to solve for "t", first by subtracting "p" on both sides, like this:

`\begin{gathered} A-p=p-p+prt \\ A-p=prt \end{gathered}`

Now we will divide both sides of the equation by "pr"

`\begin{gathered} (A-p)/(pr)=(prt)/(pr) \\ (A-p)/(pr)=t \end{gathered}`

A thus we found a relationship for "t".
