9 out of the 15 runners completed the time trial between 52.0 and 53.9 seconds so 9/15 is the percentage you are trying to find. If you divide 9 by 15 and then multiply the decimal by 100, you will have your percentage.

Answer:

$2,617.50

Step-by-step explanation:

Using this table, the tax is ...

tax = 2% × $3000 + 3% × (5000 -3000) + 5% × (17000 -5000) + ...

5.75% × (50,000 -17,000)

= $60 + 60 + 600 + 1897.50

tax = $2,617.50

__

<em>Additional comment</em>

Above $17,000, the tax is more easily computed as ...

tax = (5.75% × income) - 257.50

Each tax bracket can have a simplified formula like this.
