Juliette and Trish are selling cupcakes and cookies for a student government fundraiser. So far, Juliette has made more than $20 selling 25 cupcakes and 10 cookies. Trish has made over $30 selling 75 cupcakes. Write a system of linear inequalities that models this situation. Let x represent the price per cupcake, and let y represent the price per cookie. One possible solution to the system of inequalities is (6, 8). Are the values for this solution reasonable? Explain your reasoning.

a. -1.5x + y ≤ 5, x + y ≥ 1, x ≥ 0, y ≥ 0; Yes, because the values are within the feasible region of the graph.
b. -1.5x + y ≤ 5, x + y ≥ 1, x ≥ 0, y ≥ 0; No, because the values are outside the feasible region of the graph.
c. 1.5x - y ≥ 5, x + y ≤ 1, x ≥ 0, y ≥ 0; Yes, because the values are within the feasible region of the graph.
d. 1.5x - y ≥ 5, x + y ≤ 1, x ≥ 0, y ≥ 0; No, because the values are outside the feasible region of the graph.
