Jayden is shopping for notebooks and binders. Notebooks cost $3 and binders cost $5. Jayden has $30 to spend and needs to buy at least 3 notebooks and 2 binders. First, choose variables to represent the number of notebooks and binders that can be purchased and define them here. Second, using the variables you chose, write the linear inequality to model how many of each Jayden can buy. Third, represent constraints on the variables using inequalities. Finally, answer the question: How many of each (notebooks and binders) can be purchased?
