9. This piecewise function represents the Social Security taxes for 2009. How much did Rachel pay in Social

ANEK [815]

Answer:

Option c.

Step-by-step explanation:

It is given that the piecewise function represents the Social Security taxes for 2009.

$Tax=\begin{cases}0.062x & \text{ when } 0< x < 106,800 \\ \$6,621.60 & \text{ when } x > 106,800 \end{cases}$

We need to find Rachel's security tax if she earned $102,000 in 2009.

Since 102,000 lies in $0$ , therefore

$Tax=0.062x$

Put x=102000.

$Tax=0.062(102000)$

$Tax=6324$

So, the Social Security tax is $6324.

Therefore, the correct option is c.
