The Price of the dress = p.
To "mark down" is to reduce the price, in this case by 30% = .30.
New Price = p -.3*p = .7p
.
I guess it still didn't sell, so they marked the price down by another 20% = .20.
.
Last Price = .7p - (.2*.7p)
Last Price = .7p - .14p
Last Price = .56p
.
So the combined mark downs amount to 30% + 14% or 44%.
.
Done
