Final answer:
To determine the percentage of Starbucks' net revenue spent on advertising in 2021, the specific annual revenue and advertising expenses are needed. These are not provided in the references, and would likely be found in Starbucks' annual report. Once obtained, using the formula provided above will yield the desired percentage.
Step-by-step explanation:
To calculate the percentage of Starbucks' total net revenue spent on advertising using the 2021 data, we require two pieces of information: the total net revenue of Starbucks for the year 2021 and the total advertising expenditure for the same period. Once we have these figures, we can use the formula:
Advertising Spend Percentage = (Total Advertising Expenditure / Total Net Revenue) * 100%
However, the provided references from sources like Kantar Media, Statistica.com, and eMarketer.com do not contain specific data on Starbucks' revenues or advertising spend for 2021. To accurately answer the student's question, these specific financial figures would typically be found in Starbucks' annual report or on a financial data platform.
Once the actual revenue and advertising numbers are found, the calculation is straightforward and provides insight into the company's marketing investment relative to its sales.
