i want to sell my handphone. actually, i buy this phone at RM650. i already used this phone for 4 years. so i want to sell it with 20% markdown base on old price. what is the net price after the markdown?

calculation:

MD=OP-NP MD=markdown, OP=old price, NP=net price

20%(650)=650-NP

<:AtomicElement> 130=650-NP

<:AtomicElement> NP=650-130

<:AtomicElement> NP=RM520

<:AtomicElement>

<:AtomicElement>so i will sell this phone at RM520
