Beth purchased $21.25 worth of groceries. The sales tax rate is 7.5%. What was her total bill?
The tax is calculated by 0.075 * 21.25 = 1.59375 or $1.59. So the total bill is the cost of items purchased plus tax, which is $21.25 + $1.59 = $22.84.
Back to your question:
What is the total cost of a sweatshirt if the regular price is $45 and the sales tax 5.75%
The tax is calculated by 0.0575 * 45 = 2.5875 or $2.59. So the total bill is the cost of items purchased plus tax, which is $45 + $2.59 = $47.59
Hope this helped! Good luck!
