after a 7% increase in salary, laurie makes $1647.80 per month how much did she earn per month before the increase

Laurie's original salary before the 7% increase was $1540 per month.

What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.

Let's represent Laurie's original salary "s".

We know that after the 7% increase, her salary is $1647.80 per month.

We also know that the increase is 7%, so the increase can be represented as 7/100, or 0.07.

We can set up an equation to represent the information we have:

s + s × 0.07 = 1647.80

To find the original salary, we can subtract the increase from the final salary and set that equal to the original salary:

s = 1647.80 - (s × 0.07)

We can then solve for s:

s = 1647.80 / 1.07

s = $1540

So, Laurie's original salary was $1540.
