Final answer:
The inverse demand equation, obtained by solving the given demand equation Q = 25 - 0.25P for P, is P = 100 - 4Q. This expresses price as a function of quantity demanded.
Step-by-step explanation:
To answer the student's question about the inverse demand equation, we first have to solve the given demand equation for P (price). The student provided the demand equation as Q = 25 - 0.25P. To find the inverse demand, we solve this equation for P. Here's the step-by-step solution:
- Start with the original demand equation: Q = 25 - 0.25P
- Add 0.25P to both sides: 0.25P + Q = 25
- Subtract Q from both sides: 0.25P = 25 - Q
- Finally, divide both sides by 0.25 to isolate P: P = 100 - 4Q
So the correct answer is d) P = 100 - 4Q. This inverse demand shows how the price P can be expressed as a function of the quantity demanded Q.
