Answer:
The answer is part B
Step-by-step explanation:
The equation given is y = 4500 - 450p
y is the no of demand units
p is the price
let price be 1 dollar.
Therefore,
y = 4500 - 450x1
y = 4050
Now, let the price be 2 dollars.
y = 4500 - 450x2
y = 3600
Subtract the two values and the answer is 450.
This means that for each dollar increased, the no of demand units falls by 450
