Solution
To solve this problem, we need to determine the expression that represents the total amount Amadou paid, including the 6.75% sales tax.
-
Cost before tax:
- The total cost of the folders is (where is the number of folders).
- The total cost of the markers is (where is the number of markers).
- So, the total cost before tax is .
-
Sales tax calculation:
- The sales tax rate is 6.75%, which is equivalent to 0.0675 in decimal form.
- The tax amount on the total cost is .
-
Total cost including tax:
- The total amount paid, including the tax, is the original total cost plus the tax amount:
- This can be factored as:
So, the correct expression that represents the total amount Amadou paid, including tax, is:
