Let
be the unknown number. So, three times that number means
, and the square of the number is 
We have to sum 528 and three times the number, so we have 
Then, we have to subtract this number from
, so we have

The result is 120, so the equation is

This is a quadratic equation, i.e. an equation like
. These equation can be solved - assuming they have a solution - with the following formula

If you plug the values from your equation, you have

So, the two solutions would be


But we know that x is positive, so we only accept the solution

Answer:
About 32% of her pay was deducted ⇒ 2nd answer
Step-by-step explanation:
Lisa’s gross pay was $1204.89
Her net pay was $818.44
We need to find the percentage of the amount deducted from her pay
<u><em>Lets calculate the deduction amount</em></u>
The deduction amount is the difference between the gross pay and
the net pay
∵ The amount deducted = gross pay - net pay
∵ Gross pay = $1204.89
∵ Net pay = $818.44
∴ The amount deducted = 1204.89 - 818.44 = $386.45
<u><em>Now lets find the percentage of the amount deducted </em></u>
∵ Percent of deducted = [amount deducted/gross pay] × 100%
∵ The amount deducted = $386.45
∵ Gross pay = 1204.89
∴ Percent of deducted =
× 100%
∴ Percent of deducted = 32.07%
<em>About 32% of her pay was deducted</em>
