Answer: Total cost incurred on new laptop is $318.
Explanation:
Since we have given that
Cost price of new laptop = $300
Sales tax = 6%
total cost of laptop including the sales tax is given by
[tex]Cost\times \frac{100+\text{ sales tax}}{100}[/tex]
so,
[tex]\text{ Cost price including the sales tax }\\\\=300\times \frac{100+6}{100}\\\\=300\times \frac{106}{100}\\\\=\$318[/tex]
So, total cost incurred on new laptop is $318.
