Answer 1

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

Explanation

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 amount of the state sales tax $=\ 124.59*7.5\%= \ 124.59*0.075=\ 9.34425$

and the amount of county tax $=\ 124.59*0.5\% =\ 124.59*0.005 = \ 0.62295$

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