Allen enjoys gardening. Every sunflower plant he waters requires 0.7 liters of water, and every rose bush he waters requires 0.5 liters of water. Allen has a total 11 liters of water for these plants.  Write an inequality to represent the situation.

• 0.7s - 0.5r ≥ 11
• 0.7s + 0.5r ≥ 11
• 0.7s + 0.5r ≤ 11
• 0.7r + 0.5s ≤ 11

You are running the concession stand at a basketball game. You sell hot dogs for $2 and sodas for $0.75.  To cover overhead expenses, you need to make more than $180.  Write an inequality to find how many hot dogs and sodas you need to sell. Let x equal the number of hot dogs and y equal the number of sodas.

• y > x + 180
• x + y > 180
• 0.75x + 2y > 180
• 2x + 0.75y > 180
