Question

Meghan is running a lemonade stand to raise money for her school. On average, 45 people buy her lemonade, but this can vary by as much as 8 people. What are the maximum and minimum numbers of customers Meghan should expect?

Answer 1

Answer:

max 53 and min 37

Step-by-step explanation:

Let x= the actual measurement. |actual − ideal|≤ tolerance

Use an absolute value inequality to express this situation.

|x−45|≤8

Rewrite as a compound inequality.

−8≤x−45≤8

Solve the inequality.

37≤x≤53

Answer the question. Meghan should expect a maximum of 53 customers and a minimum of 37 customers.
