Detailed Description

Example: Grocery puzzle

A kid goes into a grocery store and buys four items. The cashier charges \$7.11, the kid pays and is about to leave when the cashier calls the kid back, and says ''Hold on, I multiplied the four items instead of adding them; I'll try again; Hah, with adding them the price still comes to \$7.11''. What were the prices of the four items?

The model is taken from: Christian Schulte, Gert Smolka, Finite Domain Constraint Programming in Oz. A Tutorial. 2001. Available from: http://www.mozart-oz.org/documentation/fdt/
