Lesson Excerpt
1. Teacher writes the words “supply”, “price” and “demand” on the board for the students to write in their journals and then write the definition for each word Supply: the amount of an item [good or product] that the store has in stock [in their store presently in their inventory]
Demand: the amount of people who want to purchase the item/good/product
Price: the amount of money the item/good/product costs.
