Solve the following formula for $t$. \[ C=W+W r t \] $t=\square$ (Simplify your answer.)

Step 1 ：Given the equation \(C=W+Wrt\)

Step 2 ：Subtract \(W\) from both sides to get \(C - W = Wrt\)

Step 3 ：Divide both sides by \(Wr\) to isolate \(t\)

Step 4 ：So, \(t=\frac{C - W}{Wr}\)

Step 5 ：Final Answer: \(t=\boxed{\frac{C - W}{Wr}}\)
