Use a local holiday toy catalog or flyer (ie. Target, JCPenny, Toys R Us) with this worksheet packet to have students practice their problem-solving skills. Younger students can use it for estimating prices, older students can use it for exact calculations and you could even provide the local tax rate to calculate to make it more challenging. Could also be used with the web to investigate web-based selling and pricing. Please provide feedback -- I am a new seller.
