The percentage mark down from $68 to $44.20 is 35%
Given:
Mark down price = Original selling price - (x% of Original selling price)
44.20 = 68 - (x/100 × 68)
44.20 = 68 - (68x/100)
44.20 = 68 - 0.68x
44.20 - 68 = -0.68x
-23.8 = - 0.68x
x = -23.8 / - 0.68
x = 35%
Therefore, the percentage mark down is 35%
