11. Neil is buying cookies and brownies for his classmates and can spend no more than $56. Each cookie costs $0.75, and each brownie costs $1.25. The inequality

    0.75x + 1.25y ≤ 40 represents all possible combinations of x, the number of cookies, and y, the number of brownies Neil can buy. Which of the following combinations would NOT be a part of the solution set?

• 12 cookies and 14 brownies

• 30 cookies and 15 brownies

• 7 cookies and 20 brownies

• 24 cookies and 12 brownies
