To solve A = P(1 + rt) for r, first isolate (1 +rt) by dividing both sides of this equation by P:

A/P =  1 + rt.

Next, isolate rt by subtracting 1 from both sides:

A/P - 1 = rt

Finally, divide both sides by t:

A/P - 1

----------- = r

    t

This could be written in other formats, such as:

A - P

-------- = r

Pt

Answer:

The student did not distribute properly to get A= P+Prt.

The equation can be fixed by putting a factor of P in the denominator: r=(A-P)/Pt
