Her salary is $24,080. What the Lauren's salary before the
was pay rise?

Answer 1

Given :

Salary after increase : $24080

Percentage increased in salary : 12%

To find :

The salary of Lauren before the rise in her salary.

Solution :

Let the original salary of Lauren be y.

According to the question,

$\sf \dashrightarrow y + 12\% \: of \: y = 24080$

$\sf \dashrightarrow y + \dfrac{12}{100} \times y = 24080$

$\sf \dashrightarrow y + \dfrac{3}{25} \times y = 24080$

$\sf \dashrightarrow y + \dfrac{3y}{25} = 24080$

$\sf \dashrightarrow \dfrac{25y}{25} + \dfrac{3y}{25} = 24080$

$\sf \dashrightarrow \dfrac{25y + 3y}{25} = 24080$

$\sf \dashrightarrow \dfrac{28y}{25} = 24080$

$\sf \dashrightarrow 28y = 24080 \times 25$

$\sf \dashrightarrow 28y = 602000$

$\sf \dashrightarrow y = \dfrac{602000}{28}$

$\sf \dashrightarrow y = 21500$

Hence, the original salary of Lauren is $21500.
