A=3P+5Prt

solve for P

A=P(3+rt)

divide both sides by (3+rt)

I'm still not understanding how to do this problem.

To solve the equation A = 3P + 5Prt for P, we need to isolate the variable P on one side of the equation.

1. Start by distributing P to the terms inside the parentheses:
A = 3P + 5P * r * t

2. Combine the two terms that have P:
A = (3 + 5rt)P

3. Divide both sides of the equation by (3 + 5rt) to solve for P:
A / (3 + 5rt) = P

Therefore, the solution for P is A divided by (3 + 5rt).
