Notebooks are 10$ pencils are 6 markers are 7.5 add all together for 23.5 so then you’ll create two equal fractions 8.5/100 (the tax) and x/23.5 cross multiply 23.5 and 8.5 which is 199.75 and divide that by 100 which is 1.9975 which could round to 2 dollars which would be the tax and if you add two to 23.5 you’ll get 25.5 dollars which should be your answer but please correct me if i’m wrong
