-20
Step-by-step explanation:
Absolute value is a number's distance from 0. It is always positive.
|-20|=20
|0|=0
|-10|=10
|10|=10
-20 has the greatest absolute value.
We are asked to express r in terms of A, P, and t.
We first divide both sides of the equation by t, which gives us

,
then, dividing both sides by P, we have

.
Swap the sides:
Finally subtracting 1 from both sides gives us

.
