Azim wants to buy a tablet computer that is priced at $255.25. If the sales tax rate on the computer is 8%, how many dollars and cents will Azim spend on the sales tax only? (Please include dollar sign, and decimal?)

You just purchased two coins at a price of $670 each. because one of the coins is more collectible, you believe that its value will increase at a rate of 7.1 percent per year, while you believe the second coin will only increase at 6.5 percent per year. if you are correct, how much more will the first coin be worth in 15 years?
