Starbucks has faced a growing backlash to the amount of waste created by the number of coffee cups used each year. The company set a goal to reduce the number of non-recyclable paper/plastic cups sold a day, but this goal has been difficult to meet with the growing demand for coffee. In 2011, the company sold approximately 6 billion cups a day. In 2022, the number of cups increased to 8 billion a day. What is the growth factor? Round to the nearest thousandth, a. b. What is the growth rate? c. Construct an exponential model for the average number of Starbucks coffees sold a day since 2011. Write your final answer in the form S(t) = Ca. d. In 2025, how many cups of coffee can Starbucks expect to sell everyday? Round to the nearest tenth.

Transcribed Image Text:**Educational Content on Starbucks Coffee Cup Waste Reduction**
---
**Problem Overview:**
Starbucks has faced a growing backlash due to the amount of waste created by the non-recyclable paper/plastic cups used each year. In response, the company set a goal to reduce this waste. However, achieving this goal has been challenging due to the increasing demand for coffee.
**Historical Data:**
- In 2011, Starbucks sold approximately 6 billion cups per day.
- By 2022, this number had increased to 8 billion cups per day.
**Modeling and Analysis Tasks:**
a. **Growth Factor Calculation:**
- Determine the growth factor and round to the nearest thousandth.
b. **Growth Rate Identification:**
- Identify the exact growth rate based on the growth factor calculated.
c. **Exponential Model Construction:**
- Construct an exponential model for the average number of Starbucks coffees sold daily since 2011.
- Write the model in the form \( S(t) = Ca^t \).
d. **Future Projection:**
- Predict the number of coffee cups Starbucks will sell daily in 2025.
- Round this prediction to the nearest tenth.
**Hands-On Activity:**
- Use the historical data provided to calculate and interpret the growth factor.
- Construct the exponential model and use it to project future sales.
This exercise will help learners understand exponential growth, model construction, and the impact of consumer habits on environmental goals.
