Answer:

The demabd function is:

$q(p)= -4500p+18000$

Step-by-step explanation:

The demand follow the linear equation $q(p)=mp+b$

1. When p=$2.00 and q=9000, the equation is:

$9000=m(2.00)+b (1)$

2. Whe p=$4.00 and q=0, the equation is:

$0=m(4.00)+b (2)$

3. Solve equation (1) for b:

$9000=2m+b\\9000-2m=2m+2m+b\\9000-2m=b$

4. Replace the value of b in equation (2)

$0=4m+b\\0=4m+9000-2m\\0=2m+9000\\0-9000=2m+9000-9000\\-9000=2m\\\frac{-9000}{2m}=\frac{2m}{2m}\\ -4500=m$

The value of m is 4500

5. Calculate b, replacing m:

$0=4m+b\\\\0=4(-4500)+b\\0=-18000+b\\18000=b$

The value of b is 18000
