The salary before the increase was $48000.
Step-by-step explanation:
Let us assume,
The previous salary before the increase be 'x'.
It is given that,
After increased by 16%, the salary turned to $55680.
Therefore, take the previous salary x as 100%. The increase of 16% from x will be 116%.
So, 116% of x equals to the increased salary $55680.
To find the value of x :
⇒ (116/100) × x = 55680
⇒ (1.16) × x = 55680
⇒ x = 55680 / 1.16
⇒ x = 48000
∴ The salary before the increase was $48000.
