From the sale of sleeping bags, a retailer made a gross profit of 12% of the wholesale cost. If each sleeping bag was sold for $28, what was the wholesale cost per bag?	Choose the correct choice
A) 3.0  B) 3.36  C) 24.64  D) 25.0  E) 31.36
Cost price * 1.12 = Selling price --&gt; Cost price * 1.12 = $28 --&gt; Cost price = $25.   Answer: D.   Actually even without any math only C and 25.0 make any sense, but since 24.64 * 1.12 won't be an integer ($28) then only answer choice 25.0 remains.
