Solve the problem.

The liquid portion of a diet is to provide at least 300 calories, 36 units of vitamin A, and 90 units of vitamin C daily. A cup of dietary drink X provides 60 calories, 12 units of vitamin A, and 10 units of vitamin C. A cup of dietary drink Y provides 60 calories, 6 units of vitamin A, and 30 units of vitamin C. Set up a system of linear inequalities that describes the minimum daily requirements for calories and vitamins. Let x = number of cups of dietary drink X, and  y = number of cups of dietary drink Y. Write all the constraints as a system of linear inequalities.

▸ 60x + 60y ≥ 300
12x + 6y > 36
10x + 30y ≥ 90

▸ 60x + 60y > 300
12x + 6y > 36
10x + 30y > 90
x > 0
y > 0

▸ 60x + 60y ≥ 300
12x + 6y ≥ 36
10x + 30y ≥ 90
x ≥ 0
y ≥ 0

▸ 60x + 60y ≤ 300
12x + 6y ≤ 36
10x + 30y ≤ 90
x ≥ 0
y ≥ 0
