Hello! It seems that we need a table to answer this question, but it is not given to me in your question. I will help to guide your way, though!
For percentages, we turn it into a decimal (move it 2 places to the left) and then multiply by the number. Let’s use the example of 75 dollars. To find its tax, we would multiply $75 by .06. This equals $4.5. This means that the tax is equal to $4.5. Now we need to add this tax to our $75. 75 + 4.5 = $79.5. Our total price for this piece of clothing would be $79.5.
Let’s use another random price as an example - $84.95. $84.95 times .06 = $5.097. Now we add the tax. We would get a total of $90.047 (or $90.05, since we round to our nearest tenth in money).
For your table, you would find the tax for every individual clothing above $75. Your table says to add the total tax (NOT the totals of the prices) together. So, using the numbers I did, we would add $4.5 + $5.097. This equals $9.597, or $9.60 total tax for these items. (Note: You can just ignore items under $75)
