6449.93 // you might not read what im explaining because you probably just want the answer but you get 6450 on the calculator then make 15% into decimal form which is 0.15. Subtract 6450- 0.15 and you get 6449.85. Then get 8 and turn it into decimal form which is 0.08. Then get 6449.85 and add 0.08 and you get 6449.93. Eh i never read the explanations anyways
