Answer: The sales tax on a $930 item is $65.10.
Step-by-step explanation:
Since we have given that
Price of item = $600
Amount of sales tax = $42
So, Rate of sales tax would be
[tex]\dfrac{42}{600}\times 100\\\\=7\%[/tex]
If the price of an item = $930
Then, the amount of sales tax would be
[tex]\dfrac{7}{100}\times 930\\\\=\$65.1[/tex]
Hence, the sales tax on a $930 item is $65.10.
