10% off

original price=20

tax=8.5%

percent means parts out of 100

10%=10/100=0.10

10% of 20 then tax so

'of' in math means multiply

0.1 times 20=2

10% off

20-2=18

then tax is added

8.5%=0.085

8.5% of 18=0.085 times 18=1.53

that's tax to it's added on the 18

18+1.53=19.53

the shirt costs $19.53
