I've been stuck on this one problem the entire day.
Question: If an amount P is invested at simple annual interest rate r, then the amount A available at the end of t years is given by A=P+Prt. Solve for P, in terms of A, t and r.
The closest solution I have has been:
but, finding how to remove or move the A from the P side of the problem has been an ongoing adventure.
In need of assistance, Please.
Have a Great day,
