Warm-up
What do you notice? What do you wonder?
Activity 1
Two schools buy science books for \$8 each from a publisher to sell at their book fairs. School A sells the books for \$12. School B sells the books for \$12.90
- Who do you think sells more science books? Explain or show your reasoning.
- How much profit does each school make if they each sell 35 books?
- School B sells 10 science books. How many science books does School A have to sell to raise about the same amount of money?

Plan a book fair:
-
Choose 3–5 types of books to order.
- Decide on the mark-up price for each type of book you chose.
-
Estimate how much money your school will raise as a profit with your book fair.
Record an estimate that is:
too low about right too high -
Explain or show your reasoning for the estimate. Include the assumptions you made.
