Marcella Heinz purchased office supplies at Office Emporium for $107.64. She then purchased an English-Spanish dictionary for $1
Sliva [168]

The total amount of tax on her purchases to the nearest cent will be $9.97

<em><u>Explanation</u></em>

Marcella Heinz purchased office supplies for $107.64 and then she purchased an English-Spanish dictionary for $16.95

So, the total amount of her purchases =\$107.64+\$16.95=\$ 124.59

On the total amount of the purchases, she paid state sales tax of 7.5% and the county tax of 0.5%

So, the <u>amount of the state sales tax</u> =\$124.59*7.5\%= \$124.59*0.075=\$9.34425

and the <u>amount of county tax</u> =\$124.59*0.5\% =\$124.59*0.005 = \$0.62295

Thus, the total amount of tax on her purchases =\$9.34425+\$0.62295= \$9.9672 \approx 9.97  <em>(Rounded to the nearest cent)</em>
