![**Yaster Outfitters Educational Model Analysis**
**Table: Weekly Demand and Price Data for Sleeping Bags**
- Price: $120, Demand: 210 units
- Price: $110, Demand: 250 units
- Price: $100, Demand: 285 units
---
**Revenue Model**
Using the regression model computed above, find a model for the weekly revenue, using "x" as the independent variable.
**Note:** Do not calculate another regression. Use the price equation to find a model for revenue.
\[ R(x) = px \]
\[ R(x) = (ax + bx + c)x = ax^2 + bx^2 + cx^3 \]
---
**Cost Model**
Find a linear regression model for the weekly cost data, using "x" as the independent variable.
\[ C(x) = mx + k \]
- Round "m" to 1 decimal place, and round "k" to the nearest integer.
---
**Profit Model**
Use models computed to find a model for the weekly profit, using "x" as the independent variable.
\[ P(x) = r + ux + sx^2 + tx^3 \]
**Note:** Do not calculate another regression. Use the fact that profit is revenue minus cost.
Round "r" to the nearest integer, round "u" to 1 decimal place, round "s" to 2 decimal places, and round "t" to 4 decimal places.
---
**Graph Analysis**
The graph \[ y = r + ux + sx^2 + tx^3 \] has a negative y-intercept. In the context of profit for Yaster Outfitters coming from sleeping bags, what is the interpretation of this value?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0d29bdc9-47d1-4ff2-b560-e93fe0e23599%2F502c3e18-7dd0-49eb-961d-ec6c9fc25c2f%2Fnemc5s9_processed.jpeg&w=3840&q=75)
