The salary before the raise is $\$18,500$.

Work Step by Step

Let the salary before the raise is $S$. $6\%$ of the salary $=0.06S$. Raised salary $=S+0.06S=1.06S$. From question we have raised salary $=\$19,610$. Equate both. $1.06S=\$19,610$ Divide both sides by $1.06$. $\frac{1.06S}{1.06}=\frac{\$19,610}{1.06}$ $ S=\$18500$.
