I am currently taking Geometry right now, so I understand where you are coming from. I think it's just a matter of approaching it differently. My teacher always says she is trying to get us to think, not memorize. If you think a tutor would help you, then go for it! Just make sure you are learning the material not just for the grade, but so that you actually understand it. That's the most important part. Good luck!
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!
