Book Prices
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?
