A CD was initially listed at a price that would have given the store a profit of 20% of the wholesale cost. What was the wholesale cost of the CD?
(1) After reducing the asking price by 10%, the CD sold for a net profit of $10.00
(2) The CD sold for $50.00
Profit = SP-CP
wholesale cost is cp
given
.2*wholesale cost = profit
.2cp=sp-cp
sp=1.2cp
#1
.9sp-cp=10
solve for cp=125
sp=150
sufficient
#2
listed price is not know
insufficient
IMO A
