The sales tax rate for a local county is 8.9 %
. If an item costs $361 (before tax), how much sales tax will be due?

Multiply the cost by the tax, but make sure you make the percentage into decimal form by dividing it by 100.

8.9/100 is 0.089.
0.089x361 is 32.129

Now add the tax due to the original cost.

32.129+361= 393.129

Now round your answer to the hundredths place (cannot have thousandths place when working with money)

$393.13
