When sold at a 50% discount, a sweater nets the merchant a 40% profit on the wholesale cost at which he initially purchased the item. By what % is the sweater marked up from wholesale at its normal retail price?	Choose the correct choice from the following answers:	A) 20%	B) 64.29%	C) 70%	D) 80%	E) 100%
we should be careful about what are we measuring % on/what is the base..   let the Marked up price =100..   Selling price= 100-50%of 100=50..   profit= 40%..   therefore the wholesale purchase cost= x.... 1.4x=50   or x=35.71...   marked price was 100 so ...   so answer is 64.29%..   64.29%
