The Ticky-Tacky ball point pens weren’t selling at 50 cents each at the House Mouse store. So Chuck reduced the price. The pens sold out very quickly for a total sale of $31.93. What was the sale price of a pen?
Solution
The key to solving this problem is that a whole number of ballpoint pens were sold. To solve the problem, just try prices until you find one that yields a whole number when divided into $ $31.93. You only need to try numbers less than 50 cents. It won’t take you to long to discover that
Thus the number of ballpoint pens sold was 103, and the sale price was 31¢.
