Part a)
The inequality that represents the number of folders f and notebooks n she can purchase is
Part b)
The graph is attached in figure.
Step-by-step explanation:
Part a)
Total budget of Mary = $150
Price of each folder = $2.15
Price of each notebook= $4.60
Let f represent folder and n represent notebooks the inequality will be:
We are using less than or equal to (≤) because the budget is 150. the total price should be less than or equal to 150.
So, inequality that represents the number of folders f and notebooks n she can purchase is
Part b)
Graph the inequality 2x – 3y = 12
We need to graph the inequality but in the given question the inequality sign is missing.
Considering less than equal to (≤) sign
2x – 3y <= 12
The graph is attached in figure below.
