31/40

simplify to get 155/2
divide by 100 to get 31/40
141x but idk if you are multiplying the 4x but I did
100%=9.99
×%=6.75
9.99x=100×6.75
9.99X=675
X=675/9.99
67.567% or 67.57
you could also say:
6.75/9.99=0.67567
0.67567×100=67.57%
so the markup is 100%-67.57%=32.43%
32.43%off
.......................WELL I GOT 72.8
