Question

A notebook costs $4.50 plus sales tax.after sales tax,the notebook is $4.86 what is the sales tax rate

Answer 1

The sales tax rate would be 8%.

To find how much you spent on tax in the total, you'd begin by subtracting the pre-tax notebook from the after tax notebook.

4.86 - 4.50 = 0.36

So now we know that you spent 36 cents on tax. From there, we'd divide our money spent on tax by our pre-tax total. 

0.36 ÷ 4.50 = 0.08

This means that the sales tax is 8%. 

Hope I could help!

The Rate of  Notebook Sales Tax is 8%.

What is sales Tax?

Sales Tax is a "consumption tax imposed by the Government on the sales of  Goods and Services".

According to the question,

Cost of Notebook before tax = $ 4.50

Cost of Notebook after tax = $4.86

Formula for Rate of sales tax =  (Cost of Notebook before tax - Cost of Notebook after tax ) divided by Cost of Notebook before tax.

Rate of sales tax = (4.50 - 4.86) ÷ 4.50                                        

                             =  0.08.

converting into Percentage, multiply 0.08 into 100

= 0.08 × 100

= 8%.
