• $50\ +\ 8.50b\ \ge23$

• $50b-\ 23\le8.50$

Jack has a $40 giftcard to Dairy Queen. He is buying a cake for $27. He will use the remaining money to buy as many blizzards as he can. Each blizzard costs $4.95. Which inequality below represents this situation?

• $4.95\ +\ 27b\ \ge40$

• $4.95\ +\ 27b\ \le40$

There is a deal at Walmart! If a customer spends $100 or more, they get a free $25 giftcard! Lori decides she is going to buy a $65 chair. She is also going to buy packs of water in order to spend enough money to get the free giftcard. Each pack of water costs $5.60 Which inequality below represents the situation?

• $5.60w\ +\ 65\ge100$

• $100w-65>5.60$

• $5.60w\ +\ 65\le100$
