You can put this solution on YOUR website!
Let i= markdown rate
So,
RegularPrice-%28i%29%28RegularPrice%29=SalePrice,
2800-%28i%29%282800%29=2200, EQN 1
2800-2200=%28i%29%282800%29
600=%28i%29%282800%29 ----> 600%2F2800=i%2Across%282800%29%2Fcross%282800%29
i=0.2142857%2A100
i=21.42857%, Answer
Check, go back EQN 1
2800-%280.2142857%29%282800%29=2200
2800-600=2200
2200=2200
Thank you,
