Final answer:
To solve for p, rearrange the equation by isolating p on one side of the equation and moving the other terms to the other side. Then, divide both sides of the equation by (m - c) to solve for p.
Step-by-step explanation:
To solve for p, we can rearrange the equation: mp - cp + z = s. First, we'll isolate p by moving the other terms to the other side of the equation. This gives us mp - cp = s - z. Factoring out p, we have p(m - c) = s - z. Finally, we can solve for p by dividing both sides of the equation by (m - c), giving us p = (s - z) / (m - c).
