A certain make of ball-point pen was priced at 50¢ at Chuck’s Bargain Bin, but nobody was buying it. Chuck reduced the price by putting the pens on sale, and then all the remaining pens sold for a total of $31.93. What was the sale price of a pen?
If we think of $31.93 in terms of 3193¢, then we can examine the factors of 3193 – 1, 31, 103, 3193. The only reasonable number for a sale price would be 31¢.
