Answer:
Cost Including tax would be $318
Step-by-step explanation:
Given:
Price of laptop = $300
Sales tax = 6% of price
To Find:
Cost with tax = ?
Solution:
Cost with tax = Price of laptop + Value of tax
We have to find the value of tax
Value of tax = 6% of Price
putting the value
Value of tax = 6 % * $300

= $18
Now Cost with tax = Price of laptop + Value of tax
Putting in the value
Cost with tax = 300 + 18
= $318
So Cost Including tax would be $318
