The vet told Casey that her dog should weigh at most 70 lbs. Her dog weighs 106 pounds, so 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?

The inequality =

106 - 4x ≥ 70

The number of weeks =

9 weeks

Step-by-step explanation:

The vet told Casey that her dog should weigh at most 70 lbs. Her dog weighs 106 pounds, so 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?

Let the number of weeks for Casey's dog to lose for 4 pounds be represented as: x

The goal weight = 70 Ibs

Hence:

70 Ibs = 106Ibs - 4Ibs ×x

106 - 4x ≥ 70

4x ≥ 106 - 70

4x ≥ 36

x ≥ 36/4

x ≥ 9 weeks

It would take 9 weeks for Casey's dog to lose 4 pounds per week and weigh 70 Ibs

Therefore:

The inequality =

106 - 4x ≥ 70

The number of weeks =

9 weeks
