Answer 1

I am out of my turf here but you seem desperate so...I tried...

Explanation:

The Total Revenue Function should be:
`TR=P*Q`
from the problem we have that `P=(6000-Q)/30`
SO:
`TR=(6000-Q)/30*Q`
`TR=(6000Q-Q^2)/30`

The Profit Function should be:
`Pr=TR-TC`
`Pr=(6000Q-Q^2)/30-5000-20Q`
`Pr=(6000Q-Q^2-150000-600Q)/30`
`Pr=(5400Q-Q^2-150000)/30`
