If sales tax is 9%, what is the tax on a sale of $3000

Answer: The sales tax is $270.Step-by-step explanation: If there is a sales tax, that means that the price is going to go up, the sales price for this problem is 9%. 9% as a decimal is 0.09. So all we have to do calculate the price with the sales tax is to add the 9% onto the 100% the item cost. That would give you 109% which is 1.09 times the number.So let's do 1.09 times 3000, which is 3270. To do this mentally, I know that 1 times 3000 is 3000, then I just multiplied .09 times 3000 which is 270. If you know what 3 times 7 is, then it's easy.So the sale with the sales tax is 3270, the last step is to subtract the sale with the sales tax already applied to the sale from the original price.3270-3000=270Therefore, the sales tax is $270Please give this answer the brainliest or give me a heart, if you need additional help, please contact my friend and I on Instagram. @jessmyybest
