Classwork: Today's lesson was framed in the context of a business, specifically a bakery that makes cakes. The bakery is concerned with two amounts: its Income (money it brings in) and its Expenses (money it spends). The bakery wants to make more money so they think if they make and sell more cakes, they can bring in more money. We looked at the equations for the bakery's income and expenses. We also looked at a graph and responded to questions about the situation.
