What is the total cost of a sweatshirt if the regular price is $45 and the sales tax 5.75%
bagirrra123 [75]

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!

What are the formulas for trigonometry and pythagoras?
jasenka [17]
That's not a good question at all.  It's a lot like asking
"What are the statements for News and President Obama ?"

There are at least a hundred formulas that are useful in trigonometry.
One of the most useful is:

       In a right triangle, the square of the length of the hypotenuse
       is equal to the sum of the squares of the two short sides.

Pythagoras is the name of the ancient Greek mathematician who
discovered that formula.  The formula is so useful that it's known
by his name, in his honor.
