$127.82 because if you subtract 10% of 123.50 from itself then add a 15% tip you get 127.82
The least is 0.015 because it is less than the others due to the fact that it is far away from the decimal point on the right side
#8 you do 360= 112+136+x... then you solve for x. X=112. Now you divide this by two since it is an inscribed angle. For #9 I have this very simplified work in the picture. Sorry I did not do #10
