Kudos for a correct solution. VERITAS PREP OFFICIAL SOLUTION:Solution: D. Because the price of a widget is $80 and the factory cost is $20 per widget, the profit-per-widget is $60. And since the factory needs to make up its $8000 fixed cost and then make $5440 profit, we can set up an equation:
60x = 8000 + 5440 60x = 13440 6x = 1344
At this point, you can probably get away with an estimate if you look at the answer choices. You know that 6 * 200 is 1200, so you need a number that's a little more than 200. The only one anywhere near that range is answer choice D, 224. Alternatively you could do the division to solve for x. 1344/6 = 224.
