After a $20\%$ raise, Dana's annual salary is $\$54{,}000$ . What was Dana's annual salary before the raise?

$\$43{,}200$

$\$45{,}000$

$\$52{,}000$

$\$64{,}800$

Show answer and explanation

Answer: B

Let $s$ be the original salary. A $20\%$ raise multiplies it by $1.2$ , so $1.2s = 54{,}000$ . Dividing gives $s = 45{,}000$ .

Choice A takes $20\%$ off the new salary, but the raise was $20\%$ of the original, smaller salary.
