A high-end clothing store purchased a black leather jacket for x percent less than its list price and sold it for y percent less than its list price. What was the list price of the leather jacket?
(1) y = 10
(2) x – y = 10
Breaking Down the Info:Set the list price as L. The "cost" would be \((1-x%)L\) and the "revenue" would be \((1-y%)L\). The profit can be expressed as \((x-y)%*L\).
Statement 1 Alone:We know the ratio of revenue to list price, but this doesn't tell us the list price. Insufficient.
Statement 2 Alone:We know the ratio of profit to the list price, but this doesn't tell us the list price. Insufficient.
Both Statements Combined:We are only given ratios and there is not a single quantity. Insufficient.
