Solve the formula for the indicated variable. \[ A=q n+z, \text { for } n \] The solution is \( n=\square \)

To solve the formula \( A = q n + z \) for \( n \), we start by isolating \( n \). First, we subtract \( z \) from both sides: \[ A - z = q n. \] Next, we divide both sides of the equation by \( q \): \[ n = \frac{A - z}{q}. \] So the solution is \( n = \frac{A - z}{q} \). To make this process even clearer, think of \( A \) as the total amount, \( z \) as a constant or component of that amount, which you need to eliminate to find the contribution of \( n\) scaled by \( q \). Just like in cooking, where you often have to separate ingredients before figuring out proportions!
