If Lisa’s gross pay was $1204.89 and her net pay was $818.44, about what percent of her pay was deducted?
Amanda [17]

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 = \frac{386.45}{1204.89} × 100%

∴ Percent of deducted = 32.07%

<em>About 32% of her pay was deducted</em>
