MATH(markup and markdown )
posted by FIZZ on .
3.THE markdown percent for a camera is 20%.if the new retail price is RM250, find the old retail price.

Multiply:
250*1.2 = ??
(RM250 x 120%) 
rm250/100x120 ?
is that true my formula? 
old price  x
.8x = 250
x = 250/.8 = 312.50
check:
markdown on 312.50 = .2(312.50) = 62.50
new price = 312.50  62.50 = 250 
how get .8 ?10020=80 then divided by 100 = .8 ?

I respectfully disagree, the answers are not the same
If I take a take a 20% markdown on your $300
I get $60, which would leave a new price of $240, not $250
