. Estimate the sales tax and final cost of a book that costs $12.95 with a sales tax
of 6%.
13 * 0.06 = ?
In my head -- I'd multiply 13 by 3 and then double it.
Of course the tax will be less than a dollar, so adjust the decimal point accordingly.
Nope.
That's not an estimate. It's exact. Plus -- how do you figure 7/10 of a cent?
YEah, your right
To estimate the sales tax and final cost of a book, we'll need to follow these steps:
1. Determine the sales tax rate: In this case, the sales tax is given as 6%.
2. Calculate the sales tax amount: To find the sales tax amount, multiply the cost of the book by the sales tax rate. In this case, the cost of the book is $12.95 and the sales tax rate is 6% (or 0.06 as a decimal).
Sales tax = $12.95 * 0.06 = $0.777
3. Calculate the final cost: The final cost of the book is found by adding the cost of the book to the sales tax amount.
Final cost = $12.95 + $0.777 = $13.727
Therefore, the estimated sales tax is $0.777 and the final cost of the book is approximately $13.73.
