Hey guys,
why cant the answer be A?
My solution
Price x number = New Price X (number - y) where y represnts the decrease in the number of magazines after new rate.
So if price is 1 then new price would be 2
therefore, 1 x n= 2 x (n-y)
or (n-y)/ n= 1/2
n-y/ n is nothing but change from old to new divided by old (% age change) and 1/2 would represent 50%. So, by this method A should be sufficient.
Am I missing something?
This relationship implies that the price of the magazine is inversely proportional
