amille ordered 3 cups of coffee from her favorite coffee shop in the first half of November. y the end of November, Camille had earned free refills for ordering more than 8 cups of offee in a month.

In the first half of November, Camille ordered 3 cups of coffee.

To determine whether Camille earned free refills by the end of November, we need to calculate the total number of cups of coffee she ordered.

If Camille ordered 3 cups of coffee in the first half of November, and assuming November has 30 days, we can calculate the average number of cups of coffee she orders per day:

Number of cups of coffee ordered = 3
Number of days in the first half of November = 30 / 2 = 15

Average cups of coffee ordered per day = Number of cups of coffee ordered / Number of days
Average cups of coffee ordered per day = 3 / 15 = 0.2 cups

Since Camille ordered only 0.2 cups of coffee per day in the first half of November, we can conclude that she did not earn free refills by the end of November, as she did not exceed the requirement of ordering more than 8 cups of coffee in a month.

To calculate the number of cups of coffee Camille needs to order by the end of November to earn free refills, we need to determine how many more cups she needs to reach the required total.

Given that Camille ordered 3 cups of coffee in the first half of November, we can assume the month is divided into two equal halves. Therefore, we need to find out how many cups she needs to order to reach the required total in the second half of the month.

Since Camille needs to order more than 8 cups in a month to earn free refills, we subtract the cups she has already ordered in the first half of the month from the minimum requirement:

8 cups - 3 cups = 5 more cups

Therefore, Camille needs to order at least 5 more cups of coffee in the second half of November to earn free refills.
