Final answer:
The inequality that represents Grant's total weight loss of at least 1.5 pounds per week over 8 weeks is 8p ≥ -1.5.
Step-by-step explanation:
To find the inequality that gives Grant's total weight loss, we need to consider the given information. It states that Grant went on an 8-week diet and lost at least 1.5 pounds each week. Let's represent Grant's total weight loss as 'p'.
Since Grant lost at least 1.5 pounds each week over 8 weeks, his total weight loss is 8 times the minimum weight loss per week, which is 8 * 1.5 = 12 pounds.
Therefore, the inequality that represents Grant's total weight loss is 8p ≥ -1.5.
