Abstract
I think consumer educaition should be incorporated into various subjects in highschool education.
With this view in mind, I tried incorporating economics into high‐school mathematics and researched the themes as shown below.
1. maximum value of sales
2. total revenue
3. maximum profit
4. average cost and marginal cost
l am convinced that this research will show a new direction for consumer education in high‐ school mathematics in the future.
