The vet told Casey that her dog should weigh at most 70 lbs. Her dog currently weighs 106 pounds.  Casey set a goal that he would lose 4 pounds per week. Which inequality represents the number of weeks it take for Casey's dog to reach 70 lbs?

• 106 - 4x ≤ 70
• 70 + 4x ≤ 106
• 4x - 106 ≥ 70
• 106 - 4x< 70

Michael is raising money for his football league. Chocolate bars sell for $2.50 each, and chocolate mints sell for $3.50 each. If Michael wants to raise more than $150, write an inequality showing the number of chocolate bars, b, and the number of chocolate mints, m, he must sell.

• 2.50b + 3.50m > 150
• 2.50m + 3.50b > 150
• 2.50b + 3.50m <150
• 2.50m + 3.50b <150
