Maximizing profit: selling soup
This is a problem solving lesson where students develop their understanding of the following areas:
- Drawing inferences about a population from a random sample of data
- Making and stating assumptions based on real-life situations
- Using proportional relationships to solve multistep ratio and percentage problems
The lesson looks at setting up a stall to sell soup. Students consider the costs of the business and look at methods for gathering data to help them decide on how much of each flavour of soup to prepare. They are then given data about requests for soup and a roll at a farmers market and compare their work with what happened in reality.
This is a problem solving lesson from the Mathematics Assessment Resource Service, a collaboration between UC Berkeley and the Shell Centre team at the University of Nottingham. Further information on the collection is given here.
